Ahh, Twitter. The place where people tell others exactly what they are doing, usually between 5 second intervals. Yeah, it makes sense if websites use it, but what I dont get is the people who use it to tell their friends exactly what they're doing. “I just had lunch”, “I'm walking to the computer”, “I've finished using the computer”. Like we really want to know that. What is the difference between Twitter and blogging? And if one needed to tell somebody else quickly, couldn't you just use a mobile phone? Ah, wait, you can use Twitter on your mobile phone! These sites go way over the top.
