If you ever meet me in person I can, sometimes, sound like a broken record. I am somewhat.. persistent.. in my efforts to get every single PhD student I meet on, and using, Twitter. Surprisingly, although my generation is labelled as being, 'social networkers' the vast majority of people I know and meet are not on Twitter. Facebook yes. Twitter no. Twitter is for weirdos and celebrity stalkers. Oh my friends, how much you are missing out. Do you know that Professors are on Twitter? PIs are on Twitter? Post-docs are ADVERTISED and links made for post docs in the future are made through Twitter. (Sometimes I get a *gasp* at this stage, especially if the person I am talking to is a final year PhD student). Next question, so how do you DO it? How do you USE it? What happens in Twitter world? My response.. Twitter is what ever you want to make it, and it is up to you how you use it. You could use it to talk to the other three people in your lab and your mum. If you wanted to.
