All of: 1) assembling a usefully-large initial dataset to gain traction, 2) keeping it updated, and 3) content moderation & anti-spam Seem super dull and tedious for project that's probably going to fail, and there's little about the rest of the process of building an improved Goodreads clone to offset that and make it enticing to work on.
