The first thing I notice is that your site takes super long to load. Are you running a zillion plugins? Something’s definitely broken since it takes thirty or so seconds for a page to load. Just the resource listing along for a page uses resources from all kinds of external sources (disqus.com, facebook, google, gigya, etc).
Turn that stuff so you only have to deal with your own site for troubleshooting. Actually, turning off those resources might just clear things up for you.
