I'm pushing less into Social Media these days. I've had huge growth on Behance in the past months, simply because Ive actively posting work in the portfolio and work in progress sections (WIP on Behance is like an Instagram story). Behance is great because you can create your own portfolio site on it too and you can communicate with other artists on it. You can build a little community on Behance too.
Don't use DeviantArt, I was on there many years ago and deleted it and recently and deleted it again too, that site is a cesspool and it's full of pornographic art. The redesign is awful, full of bugs and it's just a horrible site to use. I got blocked several times in the forums just for sharing my art, when it says its a community it makes zero sense to me. I can't even view the site on my phone because my ISP views DeviantArt as a porn/adult site.
Twitter is ok, it takes time for me to build a following on it.
Also Instagram is going weird these days...its like its full of bugs because my follower count changes a lot (it goes up and down)
I watched this video by Dave Morrow on Youtube. He makes some brilliant points on Social Media and honestly, Im beginning to feel the same way about it in the last year. https://www.youtube.com/watch?v=qMKZa-yPvUA
He makes wonderful points on the usage and leverage of it.
Hope my feedback helps!
