twitter (n.) a small tremulous intermittent sound (as of birds) / a light chattering.
twitter is a free social networking and micro-blogging service that allows users to send “updates” (text-based posts up to 140 characters long) via sms, instant messaging, email, to the twitter website.

currently i am using twitterrific from icon factory for my twitter. it features quite nice user interface with some useful shortcuts such as i can press ⌘2 to instantly reply to selected message without typing specific @username. i also have twitterberry software on my blackberry phone. although i do hope that orangatame would release an update soon because version 0.5.2 is unable to refresh the page automatically.

and you might want to check out twittervision, a real-time geographic visualization of posts to twitter (twitter + google maps) isn’t it nice to see twitter balloons popping up here and there? i mean if you had all the time in the world to spare, you could just keep watching it all day long, to see what people around the globe are doing.
