It never worked for me. Never tried it with Twitter, but I did with FaceBook and Linked In. I have three different streams of work - full time I work in international aid at MEDA (www.meda.org), I do some freelance journalism (www.scottaruddick.weebly.com) on the side and also teach part time at a couple of universities. For a while, I tried to have two seperate FaceBook and Linked In accounts, but it kept getting messy and people who searched me on either would get the wrong profile popping up. I finally just gave up and consolidated. Lesson for me is that I think it is a good idea if you are able to differentiate your various activities enough in name to allow the intelligent 'net search features I hear so much about actually be at least a bit clever.
