I still don't get twitter for people who arnt famous at least in some way... Like who the **** cares what I think about in general? No one, other than my better half... And even she wouldn't need to subscribe to a micro blog of mine...
I have a twitter purely to follow Internet people I like and websites I follow in order to get quick updates on things, also for contacting and following support networks so I know if (for example) PSN is going to be down tonight or something
