Twitter is becoming more and more popular due to its requirement as micro blogging is not much, only 140 characters that even less than a text message limit which is 160 characters. Blogger that is not writing often sometimes have no idea what to write, hence with setting the limit to 140 characters, it helps micro blogger to post whatever tweet they want without the guilty feeling that the post content does not have much value to the audience.
Automattic see this needs and launched their micro blogging theme called P2 for WordPress.
P2 is a theme for WordPress that transforms a mild-mannered blog into a super-blog with features like inline comments on the homepage, a posting form right on the homepage, inline editing of posts and comments, real-time updates so new posts and comments come in without reloading, and much more.
This is really cool. I think this is a great idea and I am going to have to try it out now! Thanks!
