This /. discussion about the post-Google Reader world has some people complaining about the 2-week age limit for new stories. How about having premium subscribers get a longer age limit?
Guess I wasn't clear -- I mean being able to turn off the training feature for my account only. It's not something I really use, and in that other long thread about the 2 wk limit you said something that sounded like the training feature is one of the reasons for the performance issues, so I'm wondering if it would help to be able to disable that feature for individual accounts.
