Yep, agree with JM and Ray there. Avoid Facebook like the plague. Apart from this Forum, I am a member of a Vintage Electronics Forum which is very strictly moderated (absolutely no straying off topic there!!)
I also look at Twitter - I find its a lot more factual and without the bitchiness of Facebook. Mainly pubs - its very good for finding out which beers they have on offer. I most certainly don't look at the 'celebs' give them a wide berth too. 90% pubs, Carol is on there, Broads Authority, EDP and one or two others. That's about it. Otherwise in the pub!
