The book I read to research this post was How To Use Pinterest For Marketing Purposes A Beginners Guide by Jeff A Hamilton et al which is a very good guide which I bought from kindle. Pinterest has 21 million members and is the fastest growing social network on the planet behind Facebook & Twitter. It's even bigger than linkedin & google+. Added to that where is an unusually high proportion of women and people into things like crafts, the right product can really sell like hot cakes. To get an account with Pinterest they have to give you an invite which isn't a problem and you have to link it to your twitter and facebook accounts to help them avoid spam accounts. When you go on the website there is a kind of revolving display of popular repins and you can either repin, follow or comment on an item you are interested in. A lot of people look for a narrow niche they are interested in and concentrate on that. Whatever you offer on this site has to be interesting and avoid spam as this site is very much geared up to penalize that and most members are very much against it. With the right product marketed in the right way you can get a lot of business. A lot of what this site is about is giving something back whether that be special offers, free gifts or free information etc. One word of caution be careful what you repin, you can repin ie someones website but that can infringe on copyright and the same goes for images. Pinterest make it clear in the event of a lawsuit you are responsible for any legal costs etc although if they are sued they will defend their interests. There is no cut legal agreement as tried and tested in the courts so you must be careful. I don't currently have a pinterest account as I think it would be difficult promoting my blogs on there but it does look interesting as a source of information. I did really enjoy reading this book which I think was free and I would recommend it
