Thanks for the answers. At least I see I'm not alone in having trouble choosing!
I did have a look in the writer corner here and did indeed stumble upon some books that sound interesting. With a bit of time I guess I can stumble on something that really catches my fancy.
Downloading freebies is not a solution for me: I know I'll download tons of them and never get to actually read them, so I'm aiming to get only those I plan on reading soon.
As for recommandations here, it would be neat to have a 'self-published' tag to help find the recommandations (but then it's probably impossible to have such a tag without adding tons of others, making them useless in the end).
I've had a look in smashwords.com and did stumble on one or two books that look pretty interesting, I'll keep looking from time to time. I'd like to make a reading resolution of reading at least one self-published book every two months, I'll see how it goes (and I'll be sure to recommand the ones I like here of course
