Your plugin is really good, I hope that there will more more plug-ins out soon by you. I have been using this plug-in without any problems.
I was lucky as my theme already included some of social sites icon, i just has to get running with my current id.
I have been organizing this categories through the menus, which makes its very neat and simple to organize all the posts on the blog.
Even I had a theme which was broken and I was looking for the solution all over the web, but there was no answer and this is the reason i had to get a new premium theme.
