I have the newest stable version of WordPress installed. Even with previous versions though, I had this issue. There are 2 issues:
1) When I post something new on my blog, it usually (always? I think...) takes HOURS for it to show up on the RSS feed. Sometimes it takes even longer than that. Like yesterday, it didn't show up in my reader for over 6 hours. Is there something I can do to speed that up?
2) There is an RSS feed for the comments. But say I make a post at 2:00pm. Someone comments on it that night. That comment won't show up in the comment RSS until I post my next post (whenever that may be, the next day or later that night, whatever). Why is that? Any way to make those post right away?
