Sharing your MyLot discussions on Twitter, Facebook and saving it on Pinterest

Tweet

I just realised today that you can share your discussions on Facebook, Tweet it and also save it on Pinterest - you can attribute it to sheer naivety on my part. I do have FB and Twitter accounts, but I do not use it regularly. I have never used Pinterest, though I think I opened an account with them. Do you share your discussions with Twitter, Facebook and save it on Pinterest? Does it have any benefits?
