I am a person who likes his specifics in his alternative pornography. (I would call it "furry", but there is a lot of art on this website which would not classify as "furry art", much of which I am in to.)
Like any other Booru imageboard, e621s tags can only go so far. If I am trying to find art involving certain things, such as "female ferals with male humans" there really isn't a way to search for that specifically, apart from searching "female male feral sex".
However, compared to literally ANY other Booru site, this website is god. There is a large amount of pressure to keep tags accurate and complete, which is certainly not a bad thing. Go to somewhere like rule34.xxx, a website I also frequent, and you will find a pitiful comparison. Many images are lucky to get tagged with much more than their canon, and perhaps a gender tag. It is disgraceful.
Plus, the comment section is allowed to run rampant. On e621 you don't see much blatant rping with the image, or with other commenters, and it is awesome.
Rambling aside, I just wanted to say how much I appreciated the e621 community, and those who keep the site running. There really is just no comparison.
