I used to dismiss all these social sites as I tried a few and never really understood them (Except facebook and twitter) so sort of parked them on the side and not bother
Although I have recently started using Pinterest and pinning all my products on the site.I only started with a few just to gauge how things went and was very surprised to see that people actually click on these and even puts my facebook page to shame.Also judging by the product and area someone has actually bought off me though pinterest (although can't prove it)
So it got me wondering now if I should make an effort to start using others that are as easy as pinterest. I did a search and there are well over 60 different places... What sites do you all use apart from Facebook and Twitter
