Pininterest.com? Fasinating! Try it... Ah go on, go on, go on!

I only joined Gransnet last night and when posting a response to a 'New hobbies' message, I wondered if it might get lost in the myriad of other comments.
So - for what it is worth - I thought I would start this new thread about Pininterest which is so brilliant. Here is my original posting:

I have recently been forced to retire early (arthritis) and after having three new hips (yes, you did read that right) have also been trying to find something interesting... and I found Pininterest.com!
Its an electronic bulletin board which is seriously addictive. Members post photographs/humour/decor/crafts etc and it is like having a fresh, free, fasinating magazine delivered to your laptop/pc/iphone every few hours.
Not sure how popular it is in the UK as a lot of the users appear to be based in the US, but it really is endlessly fasinating - some of their cultural ideas are more than just a tad difficult to get used to (eg the feedback of 'I want one' when a pink and black handgun was posted!!!) but I guess that is why I find it so fascinating.
In an earlier life I was an anthropology lecturer, so dipping in and out of this site really educated me.
Check it out for yourself I really would love to hear how other British viewers react!
