This may be leaping on a bandwagon, but I've been updating the blog and have added an extra layer of social media sharing. It seems everyone is using floating social buttons in the left side or right side of the page of every site or blog. I blame Mashable.
I've used a bit of common code to add a bar of social media buttons to Blogger. The bar is actually the bit that's fixed in place on screen while the rest of the page scrolls, but what's in a description?
The Social Media bar here includes Facebook Share, Twitter, Digg This and Google +1 (plus one) buttons with a live counters. It's all javascript, of course, with some cunning CSS that's fairly robust and cross-browser (I think!)
