I am not active in the SPN fandom like I was in QAF. I read (and occasionally request) fics a lot, but almost never comment on them. Now that I say that it makes me feel guilty because that was a big deal in QAF, reading without commenting. Anyway, I leave kudos on AO3, which is where I read most of the time. The tags and clicky boxes and sort features just make it so easy to find the good stuff. (My nearly complete list of favorite SPN fics is HERE, if you're interested.) I have a pinterest board which is fun to collect pictures and gifs. Useful when I want to watch a random episode but there are too many to choose from :) I find a quote or gif on my board that reminds of a good episode. And I follow Jared and Jensen on twitter and facebook. So yeah, TOTALLY NOT INVOLVED IN THE FANDOM *rolls eyes* But really, I feel like I just stalk the fandom. Anyway, what am I rambling about?
I didn't realize until very recently that the lack of female characters on SPN and how they all get killed off made people mad. Charlie was awesome and I definitely didn't want her to die, but it seems like it's not unrealistic that she would die. That everyone except Sam and Dean would die eventually. Also, even dead characters come back a lot. I recommend continuing through Season 11. There have been a lot of seriously awesome episodes this season. "Baby" was great. And "Safe House" was half flashbacks to Rufus and Bobby hunting the same thing Sam and Dean were hunting. It was really funny.
You know I'm going to ask how you see wincest actually coming about, right? :) :) :) Some fics are completely ridiculous it's true, but I've seen lots that have it happen in lots of different ways that all seem sort of realistic. Well, you know, brothers-who-hunt-the-supernatural-and-have-lived-the-crazy-lives-they-have-lived "realistic". See my favorite fic list for examples! Sometimes comes to mind in particular. That one is super short. The Last Outpost of All That Is is another one, but that one is epic-length.
I find the show satisfying and I find fics that just expand on their canon relationship even more satisfying than wincest fics. But the wincest gets me somehow too! (Out of curiousity I just counted them out from my SPN favorite list: out of 41 fics 18 are wincest.)
