RSS feeds for user blogs need longer time frame
Glad to see RSS feeds for individual blogs. However, it seems like either only posts to the new site get listed or the window for syndication doesn't go back very far. My feed, for instance, (http://hastac.org/blog/1389/feed) only lists one post.
This might have been a bug. The site is set to show the last 10 posts in feeds by default, and when I look at your feed I see 10 posts going back to February 2010.
Let us know if you still have problems with this.
