On Maintaining httpd Logs...

A nameless submittor dropped this in my in-bin: "I help run a site that's rapidly gaining popularity. However, I wonder how other people out there handle the large amount of logs that are generated on a busy system. How long to do you keep all those Apache logs? What about the messages logs, etc? They take a lot of space and quite often I just don't they they're worth keeping around. Thoughts?" My thoughts on this are simple: If you are serious about your site, then the logs are worth keeping. You don't have to keep them online (tape backups work well here), but the statistics within can give you valuable information on the future handling of your site. Any other thoughts?
