I think we're stuck with syslog, but for app logging, ad-hoc database storage --- especially if you have either (a) a database optimized for message queueing or (b) a schemaless database --- is going to tend to beat syslog. You're not going to realize it until you need the information you're logging, though; until then, it's going to seem like syslog is everything you could reasonably need.
