The WSJ on twitter

Jessica E. Vascellaro put together an interesting article for yesterday's Wall Street Journal called "Twitter Goes Mainstream".  She points out that the micro-blogging service has enjoyed phenomenal growth over the last few years.  While twitter doesn't release usage figures, they do say that the number of users has increased sevenfold in the last year. 

Vascellaro cites several cases where businesses are using twitter to communicate internally, to communicate with customers, or as one way of keeping track of what's being said about them online.

So, how does it work?  As usual, Common Craft has an excellent tutorial which I've included here.  We've posted here before on how twitter works ("So What's this 'twitter' I Keep Hearing About?" and "More on Twitter), but the WSJ article and the Common Craft video offer some good additional points.
