Michael Arrington of the popular tech blog TechCrunch just twittered the following:
I’m now using the techcrunch toolbar to post to twitter. awesome http://www.techcrunch.com/t…
However anyone familiar with Twitter will know that each tweet, when listed on the Twitter site, will also tell you the source; the piece of software used to post it. In the case of Mike’s tweet, Twitter informs us that he used a service called BeTwittered, not the TechCrunch toolbar.
