I watched New Tricks last night which had an angle on Twitter....
I have never given it much thought until then so had a look this morning and have now signed up. I'm not convinced that I'll tweet much (argh... I hate that terminology) but I'll certainly read - not sure what the bird equivilent of that is - I suppose listening !!
I am nosey so this might give me a fix on other peoples lives, so sad !!
