I’ve seen a few other feedback items debating whether feeds should have a limit on unread story count or a limit on how old stories can be before they disappear or get marked as read. I honestly don’t care which is implemented, but what I do care about is that the limit is, at present, too low.
I am very busy during the week and tend to catch up on my news over the weekend. For feeds like HackerNews, the apparant 200-story limit causes me to miss out on things after only a few days, let alone a few weeks (as would happen during a vacation).
Please up the limits if at all possible. Data loss is no fun. I would happily pay a little extra to offset storage costs.
