Nothing wrong with following famous people if you're interested in what they have to say, but trying to talk with them is a bit sad. I enjoy the tweets of Ricky Gervais, Charlie Brooker, Prof. Brian Cox, and various others, but I'm not trying to be their friend. Mainly though, it is just handy for having all of my news sources in one place.
Yeah good point. It's who you follow really. Ricky Gervais is a good follow, mainly football journalists are my key sources for information, and they have better views than the usual pundits.
