It was a real pain to add the +1 button and make it fit in layout and get along the other buttons alignment. But what I noticed once I finshed spread it all over my site is a horrible slow down in page load.
All page loads fast, but the +1 button is the last one in loading and while it does leaves the page like frozen until it does completely. For instance the main navigation menu (pure css) won't show subitems until the +1 button finally appears.
Code I have just before <body>
<!-- google+1 --><script type="text/javascript" src="https://apis.google.com/js/plusone.js"></script>
Then
<g:plusone size="medium" count="false"></g:plusone>
That's pretty bad news to me. Anybody experiencing same thing? Any way to fix that up?
