Ten Reasons Why Twitter Rocks | HaveMacWillBlog (aka Robin Bloor’s Blog)
Since then I have found other reasons why Twitter is not just a good idea, but imho destined to grow much larger than it is now. Here’s a list…
*[my favorite one is:] It is fundamentally social in a way that other social media web sites are not (Like Facebook, MySpace etc.) You can form groups with circles of friends on those web sites but you don’t meet new people. If you want to meet new people on Twitter, just ask a question and someone will chime in with an answer.(You need to have built up a bit of a following for this, but it works.)
Read the entire article for the full list, and hopefully it will explain more about Twitter to my friends and clients who are not yet trying this out.
