Assuming I were actually using this at work, it's not powerful enough for what I'd need.  At the very least, it needs configurable output filenames and rules-based log rolling.  Fancier stuff like multiple formatters and sinks would be significant as well.  Say I want the logger to dump to syslog on Unix or the Windows event logger, for example, plus console, file, and a user-defined location like a remote service with a socket API.  Synchronous or asynchronous logging for high-latency writes would be important, unless that was left up to the user-defined sink implementation.  Finally, I'd need some way to log to different sinks based on some rule.  Say I want data for each user in a separate file, for example.  Boost.Log is almost too configurable in this regard, and comes off as overcomplicated, but it does all this and more.
