P2 is a powerful WordPress theme useful for group collaboration, a kind of combination of blogs and Twitter.
At first glance it might come across as another simple Wordpress theme, but if you take a closer look, P2 has a lot more to offer.
In simple terms, P2 is like a combination of Twitter and blogs. Instead of long, monologue posts, P2 is for group bloggers. It features inline comments on the front page for easy group interaction. It does everything that your standard blog does, but faster.
P2 does away with logging into your post editor. Logged-in users can post directly on the front page. Posts are published in real time and the page is updated automatically with no refreshing.
P2 also features an effective iPhone interface. It’s from Automattic, the makers of WordPress. If you’re working in a small team it’s worth experimenting with.
