Yeah, libraries aren't a good way to start because there's not enough interest in using them.

There are opportunities to build standalone tools which blow away their predecessors by multiple orders of magnitude, though; after getting enough researchers to use one such tool, you might attract sustained curiosity from a few people wondering "how the hell did s/he do that?!" and organically grow a small library with a real user base. That's one of my own long term goals, anyway.
