As someone who is pretty active here, but who does a ton of fanfic reading. (And used to write, maybe will again. Maybe.) I think I prefer to read the description here and click a link. I tend to keep tags organized by site, and I don't associate Imzy as a reading a long thing site. AO3 is just too easily customizable in comparison. Especially when it comes to chapters.

Thanks for this answer and your reasoning!
