Wk7 Twitter

Well I've spent a few days now Twittering, and I can honestly say that it's not for me. Apart from not having the time, I still cannot see the point of advertising what I'm doing, or thinking to the rest of the world! Then tonight, I added a couple of comments and I receive a message via gmail that John Chandler, a bio paint sprayer (whatever that is!) is now following my Tweets - I haven't a clue who this person is and it's freaked me out, so I won't be carrying on with Twitter.....
