I have noticed more than a few people not playing nice with the apis. It is not nice to hit an rss feed once per second or once every 2 seconds. I have set minimum times for each to 10 minutes. So, hammering the site, will get you nothing, except banned.

Those of you playing nice with the apis, cool, you won't see any change. Those of you are not, fix your apps and set your retry times accordingly.
