I think there are many books out there that aren't exactly masterpieces, put out there by big publishers. Conversely, works that are big commercial successes were for a long time shunned by publishers (JK Rowling). Perhaps user reviews & ratings, and previewing books would be a good enough filter? I mean people can already publish anything they want for free online, and non-techies seem perfectly capable in filtering out.
