I'm into stats and looking at Google Trends and this is something I've been wondering.
I mostly reverse image search what I see on 4chan, dig through the pic's booru tags to see if I like more, add negative tags as needed, and add the link to a text file for downloading. (or an ever-growing "later" text file for tags I don't have the patience to sift through at the time). Sometimes I use Kemono as well.Doujins are good too but I'd rather get to the meat of it than read a story, though sometimes story helps a lot.
