Like my colleague, I am also a late joiner in the Twitter dance. I had always been reluctant to join the micro-blogging phenomenon (I started this blog 3 years ago) but was finally intrigued by the fact that the company would stop delivering SMS alerts for free outside the US. So, I decided to discover it by myself a month ago. I am still not 100% convinced but begin to see the value from a PR / news / interaction perspective.
