I resisted for a long time as I didn’t see the usefulness but I am now on Twitter and posting once in a while. My Twitter page is http://twitter.com/pixelyzed
I would have given up almost right away if i’d had to do it through the Web interface but I found a great Twitter client called Twhirl based on Adobe Air which makes the experience a lot more fun for me.
I’m planning a design refresh of this site (as well as my professional freelance site) and I may add the Twitter thing to it then but I’ll see.
In any case, Twitter turns out to be far more interesting than I expected so I’ll stick to it for now.
