In fb - it's my groups that keep me there. People actually talk in them and I get all kinds of tips and tricks on various topics. The art sites are vanity projects for me. I have an account at insta, but I don't think my work fits the platform.

For LinkedIn - I'm using the LinkedIn share feature here at steemit on my posts that make sense to be seen on my LinkedIn profile. I have no idea if that gets me any views or any benefit but it is easy, so I'm doing it :) That place is necessary for me, but I sure don't see much return out of my efforts. I had a guy try for internet sex there a few years ago. That is about the most interesting thing from the decades I've been a Linker lol.
