I am a sometimes twitter user but only two other people I know regularly post. I have very few actual followers myself. I follow a few people to see updates to their podcasts and blogs but have notifications turned off so I only see things when I remember to. I see twitter handles and hashtags on websites and posters everywhere but do not know anyone that actually uses them.
