Facebook does not have any relationship to either. It's a "fun" place to be hanging out, which is why so many people are there. We could all make a long list of reasons why we are on there. My own list would be pretty long. Including things like how amazing it's been to meet so many artists, before I've met them in real life. It's a good place to see what's going on in the art world, and to share art. It gets you lots of positive feedback, which is very nice. And it serves as the social outlet for many of us who aren't surrounded by others in our daily work. To be honest, it's a way to keep from being lonely, socially.
What are the negatives? The rest of it. Most importantly, the amount of time spent browsing and or responding to commentary, is time that could be spent in other interests I have, that I have let slip away, because of the time FB takes away from me. That means time to read more, time to involve myself again in many of the hobbies that I've ignored since I let Facebook eat up that time. Hey, think of the art that could be done with the time gained by not being there!
I've already had emails from well meaning Facebook 'friends' making me feel like I've done something to them, by doing this, because they can't see the paintings. For them, and the others who's interest in my art I appreciate and am grateful for, check in here and on my website. Both are better art viewing venues than Facebook. And you don't have all of the political and social bullshit to have to deal with.
With that, I'm going enjoy this beautiful spring day with a painting excursion or a walk. I'll see you back here as soon as I have something to share. My studio is waiting... Ciao!
