Hey @katem, I have Facebook also but in the 4 weeks I've been on steemit have not posted once. I have changed my display name and removed every image I have there except a generic profile and background picture. Facebook is a great time-steeler. You'll spend an hour on there and have no concept of what happened around you right? Steemit makes you think, makes you experience so you have something to share.
Facebook seems to be all about how amazing your life is, or at least that's the perception people want to post there. Look where I am, look what I'm eating, look what I got... Today I drove around the countryside and engaged with life. I came home and posted to steemit. You can see my post and images on my blog called "Winters' day wanderings"...There was zero thought put into whether I should post on Facebook. Steemit just seems to have more likeminded people. It seems...More real. For me anyway. :)
You're absolutrly right, I have spent many an hour of my life on Facebook without interacting with the real world at all. It's almost like a parallel universe where people try to create a world or life they would rather be in.
The world of Steemit seems to be much more on a level with real life.
