I’ve been curating my e621 profile for a few months now, mostly to save reference art for characters I follow. It’s a handy place to organize fan works from mangaka I like, though the tagging system can get messy—I still accidentally stumble onto stuff I didn’t ask for. Still, I appreciate how easy it is to find specific series or artists. I dropped my e621 profile link in a few forum threads to share my saved collections. Honestly, it’s not perfect for mobile browsing, but for a free service it gets the job done.
