BTW one quick question, after installing the plugin it seems like at every page its interacting with twitter.com using js to refresh the cache, is that really necessary? I mean its creating a lot of stress delaying page loading and also consuming fast the API calls allowed.
IMHO I think if it actually caches just check if new tweets exist, and or use a time variable for expiration, and only if you invoke the calling page where you will actually render results, if not you will really have a lot of lost bandwidth and performance.
Hope that makes sense, thanks in advanced.
Cheers
