I really like Audiobookbay for discovering new books, but if I'm searching for something specific it is a bit annoying to navigate with their sometimes broken search and the vague categorization. Seeding is also sometimes sparse, especially with older uploads..
Does anyone know good alternatives? There doesn't seem to be an audiobook category in the megathread (yet) ;)
Another, maybe not very sustainable method, is to subscribe to audible. Use your credit to buy your desired audiobook. Then use Libation to download a copy. Return the book. Rinse and repeat until audible gets mad at you for returning so many books.
If it's like when I did it, you go into their IRC and get a basic interview. There might be a learning curve for setting up your torrent client, but the short of it is you want to respect their seeding rules else you might get kicked off. Their forums should have a guide for most major torrent clients as well.
