Edited to add - I forgot to say how I use Twitter. I haven't been on that long so my use is still evolving.
- asking and answering quick questions (Twitter is much more immediate than FT, but also more ephemeral)
- micro blogging (stuff too small for a blog post)
- learning all sorts of useful travel stuff (demographic is a bit different to FT)
- alternate news source (much more immediate than my other sources)
- etc
