Over at Information Architects, they present the case against the use of social media sharing buttons.
But do these buttons work? It’s hard to say. What we know for sure is that these magic buttons promote their own brands — and that they tend to make you look a little desperate. Not too desperate, just a little bit.
The user doesn’t come out of nowhere. We don’t land on your page and then head happily to those social networks to promote you, just because you have a button on your site. We find content through Facebook, Twitter, Google+, Pinterest etc., not the other way around.
