I've made some useful/interesting local connections and a few friends on Twitter. I think it can be useful for niche interests, be it hacking, food or music.

I've made some useful/interesting local connections and a few friends on Twitter. I think it can be useful for niche interests, be it hacking, food or music. The problem is that users need to be patient and discerning in developing a good list to follow. I've found much more value in finding new contacts on Twitter and more in maintaining distant relationships on Facebook.
