Honestly, the Larry scene can be a bit of a moving target depending on what you're after. For complete, long-form stuff, I'd say Archive of Our Own is the undisputed champ. The filtering system is a lifesaver—sort by word count, completion status, or kudos to find those epic finished sagas. Wattpad has a ton too, but you have to dig through more half-finished drafts and songfics. Sometimes the hidden gems are on dedicated fansites or LiveJournal archives, though those can feel like a digital archaeology dig. I still have a folder of links I saved back when people posted on Tumblr and linked to Google Docs; the fandom really has a history everywhere.
Last week I read this 200k enemies-to-lovers coffee shop AU that I found through a Reddit rec list—it’s not on the major sites, just hosted on a personal blog. So, my advice is to use AO3 as your primary search, but don’t ignore the older corners of the internet if you’re hunting for classics. The good, complete stories are out there; you just need to be willing to sift a bit.
