I follow around 900 people, most of whom are reporters/bloggers/actors/actresses/attractive ladys/friends.

Depending what you're interested in, some favourites of mine are: @SciencePorn, @GaryVee, @TheStalwart, @AntonKreil, @GSElevator, @DavidBrent, @Cmdr_Hadfield, @FootyGif, @Digg, @GaryLineker

I always say how Twitter gets much better after following more people.
