I have met an artist or two who are on Facebook, but I'm unsure of any groups that they run or a part of.

I do not follow any Artist Group/Page on Facebook. I much prefer to follow Artists here on FA.

I've found a lot of really great art groups on Facebook but they all have their pros and cons.

I only know a few on Facebook. But know way more artists here on FA.

For me personally my Facebook connections are to family and friends who may not understand this "world" and so I would keep it separated. Also don't really have time to go to multiple different sites looking for art, so basically just hang out here.

I do not follow artist groups, but I know lots of artist who have Facebook pages, and I follow their page. I spend lots of time on facebook and my main feed mostly consists of art.
There's also lots of groups that are dedicated to art and furries. Not dedicated to one specific artist, but more like places to share your art, ask for tips and advice, discuss art but also characters....

I follow a few on Facebook and I have my own photography page on there.
