The following is suggestions based on Google page speed to your plugin:
I seems the plugin loads the Twitter buttons from different URL’s which create duplicate downloaded bytes and additional RTTs. This will lower a sites page ranking according to Google and I therefore think it could merit a fix:
Also, I use the compact twitter “tweet” button but the .css file given by this plugin has a minimum height which is a layoutproblem when I don’t use the counter of tweets. There’s simply too far a gap between my socialize buttons.
On my website Higher Studies the same problem is present. I am using tweet button on each post on home page which loads recurring but Google says its the same content and loading from different urls. Anybody here can help to fix this issue.
