I have recently been on a quest to find a new RSS reader for OS X. NetNewsWire looks to be the leading candidate, since LifeRea doesn’t have a native port to OS X. One thing I noticed in the clients I tested, is that they have fixed times when they will check ALL feeds for new content. This time increment can be in minutes, hours, days, weeks or months. Since several of my feeds get updated 1 - 2 times a month, the fixed time metric doesn’t really work all that well with those sources (especially since the time applies to all feeds). While it may take a bit of additional coding, it would be neat to have syndication clients learn how often feed are updated, and base their syndication checks around that. Hopefully the RSS reader developers will add backoff timers to their clients, which should save bandwidth, and reduce the amount of work each web server needs to do.
