I have a PR0 website www.myspooz.com and the last time the cache was updated was august 19th I have many links pointing to it,but for some reason google refuses to update the cache
hello, i have studied your site, you have done lots of keyword stuffing there.and at the bottom side you have put some hidden text. be careful and try to follow google guidelines.
google cache speed is only related with the power of backlinks. i think you must also check your robots.txt and meta tags which may block indexing
Probably has nothing to do w/ google cache, but you may want to call all of that javascript Code (markup): remotely.
