does the floating bar load asynchronously or is it blocking?
The FB Like script is asynchronous, while others are regular scripts.
I used a floating share bar from your site but am trying to remove it due to site updates. I was looking for the html coding so that I could search it in my template and erase it, but the html on this post doesn't match anything I have in my template. The widget links directly to your site, so I'm positive this is where I got it, and I didn't find any other posts that might have been the one. Did you used to have another floating share bar post, somewhere?
I only see the Pinterest hover button in your template.
