WP Facebook Timeline (MF Timeline): provides a visual linear timeline representation of your posts and media sources. You can also add content from Twitter to the timeline on your site.

Timeline WP: a cool theme that gives your website the look and feel of Facebook Timeline. It is social media friendly as well.

You certainly do not want to use these solutions on your main website. Trying to clone what Facebook is offering could cause you legal issues. But these solutions are nice to play with to satisfy your curiosity.

AskIt has a very clean look and feel to it. It has 7 color themes for you to choose from. It does have a reputation system and does allow your visitors to vote on answers others have provided on your website. The theme is quite dynamic and takes full advantage of Javascript to offer a more slick experience to your visitors. This theme’s reputation system enables your community to not only evaluate the answers people have provided but get rated for their correct answers.

The theme is advertisement friendly and offers automated thumbnail resizing. The back-end should be familiar to those of you who have used ElegantThemes products in the past. ePanel is one of the most flexible back-end systems around (allowing you to customize your website’s navigation and on-page SEO factors without needing a plugin).

AskIt for WordPress has a clean look and feel. It is a great tool to enhance your existing blog with or create a new website based on user generated content. Spam handling could be a bit better (you can address this with plugins). Still, it’s one of the more complete Q&A themes we have tested.

The theme may not be an exact clone of Yahoo! Answers, but it does pretty much give you the same functionality. The latest, popular, and unanswered questions are displayed on your home-page to encourage your visitors to get involved. You can add most active questions and top visitors to your website (via widgets).

Just like Yahoo! Answers, your visitors get to answer questions and vote on each other’s questions (vote up or down). New visitors can always register for an account, write up a question, tag it, and post it to your website. The theme also keeps track of your users’ activities on your website (in the user listing section). Your visitors won’t have a tough time figuring out who are the most helpful individuals in your community.

Answer Theme not only has a very clean design, it comes with various color schemes that makes life easier when customizing this theme. The back-end is pretty solid as well, allowing to manage your design, payment settings, and notifications.

You don’t have to settle with the look and feel that you get with this theme right out of the box. But it does beat having to write a Q&A script from scratch. Another unique theme for WordPress.

The theme is designed for those who want to build a sophisticated, yet clean looking portal. It has plenty of space for you to promote your top products and drive your point home on your WordPress site. The nice thing about the featured section is the fact that you can display multiple stories on it and even add YouTube videos to it.

iBlogPro is social media friendly as well. You can easily add your social networking profiles’ information at the top of your portal to give your visitors a better chance of connecting with you on those websites.

iBlogPro is ready for localization and is search engine friendly. What’s most impressive about this theme is its powerful back-end. You don’t have to be well-versed in PHP to customize your theme. The back-end has plenty of features to keep you busy for a while.

I used WordPress 3.0 beta to test this theme (thanks to PageLines for offering us with a test copy). As you can see in the above screen-shot, you have two pages to deal with using this theme. The Feature Setup page is all about managing the featured section on your portal. Whether you want to add content to that section, change the way it works, or add custom code to it, that all can be easily done on this page. You can change viewing time, transition time, transition effect, and even make changes to your navigation. Customizing all aspects of your navigation boxes could not be any easier with all the options available here.

What I love about this theme is the fact that you do not have to touch the code to make every little change. Changing your logo, enabling the drop down menu, and adding your social media information can be all done on through Theme Options page. Here are a few other things that you can do right from the back-end:

• Customize post/page information
• Change thumbnail options
• Customize your sidebar
• Modify your footer
• Change font/color options
• Add your favicon and Apple Touch images
• Include custom codes (including Google Analytics and …)

Here is the feature that sets this theme apart from others on the market: iBlogPro comes with an optional BBPress add-on that enables you to start a forum with the same look and feel as your portal. That means if you choose to start a forum around your portal, the look and feel will stay consistent throughout your web properties.

Overall, iBlogPro is a very well designed CMS theme by PageLines that can be used to effectively start and manage a portal with WordPress. It’s pretty affordable and comes with its own matching forum add-on. Ready to go out of the box.

Cene theme is a very similar to the previous designed used at CNN.com. It lets you promote your breaking stories at front. You also have plenty of space to discuss your other stories at the bottom of your page. The theme is video ready as well and can handle images well as well. So you can bring it all together on your news portal by adding all types of content to your blog.

Just like any top news portal, you get to display top news from all regions of the world on your website. Obviously, we are talking about how your information is categorized on your blog. So depending on the structure of your blog, these will look different on your blog. But it’s a nice way to give your visitors more ways to go through your content.

Cene theme also lets you share your talking points with the world as well. It doesn’t hurt that the theme is ad ready and dynamic. All in all, a very affordable, solid CNN clone theme for WordPress.

Fresh Tweet is not only lightweight but easily customizable. Once you install Fresh Tweet, you are going to see the similarities that it has to Twitter. But of course you’ll have your blog posts instead of tweets. Just like Twitter, you get one sidebar, on the right side of your screen. You can use it to push your ads on and monetize your blog. You can also change the look and feel of the theme so easily as the code is not particularly complicated.

Your posts pages are not too complicated either. You can easily add your images and social media icons to the end of each post without too much trouble. You can also customize your logo and other aspects of your theme fast. What I like about this theme is that it gives you the ability to create a socialize page that lets you readers get involved and leave you their thoughts and questions (just like Twitter).

All in all, Fresh Tweet is the unofficial Twitter WordPress Theme. It’s well-designed and lightweight and gets the job done. If you are a Twitter junkie, you are going to love Fresh Tweet (it’s free too).
