Twitter is white-hot popular now but I can't see it lasting really long in its present form.
I get so many people adding me to their follow list, but then when I check them out to see if I should add them or not, I find that 100% of their tweets contain a link of some sort (spam).
The people I follow are there because I think their tweets are either funny, or fall in line with my own interests. Too much spam, and I hit the unfollow button.
I'm not (yet) convinced there's much business to do with Twitter. If you disagree, then explain.
