At the top of the post, before I start scrolling down, the counter will show different a different count then after I scrolling down.
For instance on one of my posts, I showed 104 Facebook likes while static, but as I scrolled down the Facebook Like count showed only 7.
Twitter, Pinterest, and G+ all seemed to be OK.
No worries though, I really don't like the scroll or socialite feature anyway so I just disabled them.
Made a BIG difference on my page load time compared to Really simple Facebook Twitter share buttons. This plugin definitely loads faster as it uses asynchronous loading.
Using this with WP 3.8 and Solostream WP-Clear 3.2.1 theme. No problems.
