I said AO3 in parts, but I have my settings so that fics will always load on one page there. I just mean "if it feels natural to do it in parts, do that".

I like AO3 because then I can just load one page and also because I love the reading history. Everything else is fairly equivalent for reading, but I get unfortunately distracted from commenting and am much more likely to comment if I'm reading on DW or LJ.
