Just added a Google “Plus 1” or +1 link to the site. This is a way to tell your friends about the post- and if you think they should check this out. It also works on the site (which is where I think you should start).
The idea is that when you search for things- you will see if anyone in your circle of influence (friends, contacts etc.) has already liked something in your search results.
Watch this short video about Google Plus 1- and then give it a try.
