I have read in the press about how Google+ will compete with Facebook and Twitter, but I think it has arrived too late! I’m an enthusiastic user of Facebook and Twitter, both for social networking and science communication. I have 200+ contacts on FB, and 1700+ on Twitter. On Google+ I have less than 20, most of whom are also on FB and Twitter. So I see little point in trying to develop my contacts and activity on Google+, at least for the moment. I’ll keep my account there, and keep it up to date, but it won’t be the focus of my attention. Really I think it has come too late, and will have a similar fate to Wave and Buzz. We’ll see!
