I think this plugin is the best out there.But something very useful ,for me at least,is missing... it would be nice if i can change the facebook button width from inside the plugin options,because i don't know about css.... My facebook like button counter is half,and that is because my like button is very big in my language "Μου αρέσει". Οverall thanks for that plugin.
So if you think it is the best social-bookmarking plugin out there, why do you give it just 4 out of 5 stars? If you don't know CSS and how to style the various buttons, then why do you blame the plugin for that? Last but not least, you could ask for support, as a "last resort"!
