The +1 button
Reading a Tim Bray post, I figured out that the +1 button is not that useless as I thought previously. It could help improving search optimization for my blog and as everything that improves search, improves the web.
So there it is, the +1 button. I promise I will not add a lot of clutter to the blog with the "follow", "like" and all those social stuff. My personal networks are in the footer or the about page so you know where to find it. I also plan on replacing the Facebook comments with Disqus as soon as I figure out how to make it work.
