I used Reddit a few times and have an account but, overall, I don't really like the structure. I agree that it's a more closed-off community. You get more "up" votes by making snide remarks. I feel like 143K words is a lot for a first novel, but that's just me. I am in the process of revising my first book and it's grueling. I like the actual storytelling much more than the writing part. The good news is that after many revisions, you look back on the first and say, "Wow, that sucked. The revised version is much better!"
