Plaxo, Linked in, Twitter (abandoned), Facebook...frankly, the 'Cat has no reason to feel threatened by these outfits. It would be nice tohave full-featured profiles, and space for sound files (maybe a limit of ten per Catter or something like that); embedded utilities for MIDI management (playing, scoring, etc) would be fun as well.

The database, now, could be one hell of an engine not just for what it already has but also for chronologies (the ability to display hot-linkled titles for "Blues songs from 1890 to 1920 of Mississippi origin" would be a whiz, eh? Artist and repertory cross links, the ability to create subsegments of history with an "earliest known date" field...many, many possibilities come to mind.
