Twitter Fad Or Future

We can "tweet" our rants in 140 SMS-friendly characters on Twitter, make some friends while posting our resume to LinkedIn, and stay on top of every last byte of activity those friends publicize on Friendfeed and Facebook. As with all uncharted territories, these and other social media (a.k.a., web 2.0) services have attracted enthusiastic users, service evangelists, and dismissive critics. Some say Twitter and LinkedIn are the future, while others label them fads or time-sinks and question whether they are of any use whatsoever. Thing is, they may both be right.
