I added +1 and Like buttons to every post, so at least even if I don't have comments in this site, people can share it and comment in their favorite social network. Not that I post much here anyway ...

The only problem I have so far is that the contents of what you share don't seem to preview properly in either Facebook or Google Plus. They don't show the text of this post :( Perhaps they don't like PHP? I also tried adding a meta name="description", but it failed as well
