hi peoples, I'm a bit of a twitter newb and have installed the twitter app, however I don't seem to get notified of anyone tweetting. The only way I know is by going into the app and looking. Maybe that's how it is supposed to work, but I thought I would get notified of someones tweet is there a setting somewhere that lets me know if someone I am following posted something? should I get any notifications at all? or am I using the the wrong app perhaps?
