Twitter is no doubt the most popular micro-blogging service. I was a bit late to climb the Twitter bandwagon, but once I did, it really is addictive! I use Twitter to keep my followers updated with my latest posts and update if I’m doing anything interesting.
There are many services that allow you to post on Twitter without opening the main site. I use Twhirl for desktop and TwitterFox when I’m browsing in Firefox. If you are an IM (instant messenger) junkie and chat your whole day out, here’s one service that you will like which allows you to tweet directly from popular IMs.
