The new asynchronous code is indeed faster but there are still two major issues for me:

1. To increment the +1 count, the visitor must have a Google account, must be logged in to their Google account and must have a public profile. I've estimated that approximately 20 percent of my site visitors have a Google account but I have no way of knowing the number that are actually logged in and have set up a public profile.

2. The +1 code does not validate as W3C HTML 4.01 Transitional. The basic code when put into a DIV with class="g-plusone" does validate but the other parameters such as data-count="false" and data-size="standard" do not validate.
