Do you Twitter?

Twitter is one of those Web 2.0 applications that at first 
glance seems to beg the question: why? But first, a description of the service 
from its home page:
Twitter is a service for friends, family, and co–workers to communicate and 
stay connected through the exchange of quick, frequent answers to one simple 
question: What are you doing?
In short, it allows you to post a short description of what you are doing right 
now (or in fact, any short phrase at all – the trend seems to be for posting 
witty or funny comments).
The next obvious thing is to track what others are doing – which can be a 
limited set of your friends, or for anyone who has chosen to make their status 
public.
Another interesting use is to use it as a virtual SMS mechanism on the 
web – you can choose to only track your friends, and use the service to keep in 
virtual touch with each other.
Twitter offers tracking and update via the web, IM as well as SMS via a 
cell-phone.
The service has already gained a large following, and many web celebrities such 
as Marlin Mann of 43Folders fame or Cali Lewis from 
GeekBrief TV are on board.
Yours truly is also testing the waters right now, and has the handle evolve75 
on the service.
There are also quite a few tools already available to make the usage easier. A 
Firefox extension called twitbin enables live tracking via 
a side-bar on your browser, and OS X dashboard widget called 
Twadget is available for updating Twitter from your Mac desktop (for 
Vista users, an alternate version for the sidebar is available 
here).
Whether Twitter is just another Web 2.0 meme – or here to stay – remains to be 
seen. The service is useful, but carries the risk of the novelty fading away 
to becoming a chore 😦
