I currently use Bloglines as my feed reader of choice. It’s gotten the job done over the past three years, and overall I’m happy with it. But if there were a feed reader that could do the following, I’d make the switch to a new platform:

• Timed feeds. I should be able to regulate my individual feed intake. I’ve already cut down my total feeds from 400 to 40, but there are still feeds that I’d like to have updated either once a week or once a month while others get updated daily.
• Feed restrictions. This is more of an extension of the above item, but I’d love to restrict feed consumptions during certain hours (read: 9-5) to optimize productivity. Mindless thumbing through my feeds is more fun than performing menial work that still needs to be done.
• Feed priority. Again, this is related to item one, but I’d consider bumping my feeds back up if I could prioritize and time them. Tagging would be nice as well as better integration with Del.ici.ous and/or saved feed items.

Does such a reader exists? How would you improve your feed reader?
