I found this fascinating quote today:
I’m sure there are business benefits of being on Twitter and you’ll find plenty of articles on the web as to why, and how. But for me the real benefit of sticking with Twitter is the people you get to know from spending time there.Why It’s Worth Sticking with Twitter, Feb 2009
You should read the whole article.
And I wholeheartedly agree and applaud Joanna for such a great way of describing Twitter and giving first time or beginning users of Twitter a few more reasons to get on and get going with this microblogging phenomena.
