If so, what do I need? (Plugins, etc)
Please note: I am not looking to create a website similar to FB, but something similar to http://likewut.net/
Also: I know that I can add 'likes' with plugins and with code but can I add functionality? For example, can users add their own likes, or sorting (top likes, recently liked)
But Is that possible to sort the most like articles which what the mentioned example site seems to do manually. Can that be automated? I think this is also the part of the exact question.
Users can add their own likes too, you can have a post submitting form on the page itself from where you can accept likes from users.
But I am not sure about the sorting thing, I think its not possible.
Other sites do it manually, notice sometimes they have a mistake in their order.
One thing more, use wp-super-cache to precache all pages to reducen load.
I am also in queue of making one, and I can actually do the technical stuff too. Drop me an email if you are interested in doing this together.
Just had a look and realize that sorting out most liked pages is possible too :)
Install this plugin.
That's very easy: http://wordpress.org/extend/plugins/wp-facebook-like/
Now, the 'likes' will be posts with the like button attached?
Sure! However you can get FB API from http://developers.facebook.com/ .
That's similar what I gave you before..;)
On your"single.php" page temple paste this code:
<iframe src="http://www.facebook.com/plugins/like.php?href=<?php echo urlencode(get_permalink($post->ID)); ?>&layout=standard&show_faces=false&width=450&action=like&colorscheme=light" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:450px; height:25px"></iframe>
P.S. You can use it also in other page....
Nichole, you are smart enough, write it yourself.
Use symfony and mysql w/ Doctrine. The basics would take maybe 2hr. to get users (sfGuard) and walls, with comments and friends.
Every user has a wall, every wall has comments, users have friends. At it's core, fb is pretty simple.
