As of right now the only websites I really use to read fan fiction are quizilla.com and fanfiction.net. Are there any other exceptionally good sites to read from, or any sites that are your favourites?
Well, it can be a bit tricky to find sometimes, but there's a lot of fic on Livejournal. Ficwad.com is also okay, but it's not a very big site (compared to FF.Net anyway).
Archive of Our Own is a good one as well. I think it really depends on the fandom though, sometimes you need to hunt out very specific sites to find some really good stuff. Fanfiction.net is good, but it's also unmoderated, and filled with spelling mistakes, and worse.
Normally when I get a bit sick of FF.Net, I just google what I want to find, and then try to ignore the FFN links. I hope that was helpful.
if you like to read only, then i dunno any besides, yeah, quizilla and fanfiction but there are some wetpaint websites on which to roleplay fan fictions. harry potter fan: hogwartsepilogue.wetpaint.com
other wetpaint sites have pages where the members write fan fictions. dunno if that was helpful
