I'm relatively new here, and writing for pleasure, not for business, so understand that I may not be the best person to answer this.
However, I suggest that you switch from using RSS feeds to using direct URL links. Yes, this means manual updating, but that is probably a good thing. When you login to perform your URL updates, you can also freshen the other content. Fresh content is always more appealing than stale.
Note: As I was writing this, relanche also answered, and I'm sure her answer is much more relevant than mine.
