Well, I'm 64, and have been a regular FB user since 2011, but I'll give you a pass for not wanting to tackle the learning curve. I was the square peg in high school, and started hanging out at the Dartmouth College computer center in about 1970, when I was in 10th grade, so I do have a 'slight' advantage over you. lol. I would likely feel a bit overwhelmed by computers in general, and facebook if I was just getting into the whole thing. But FB has been a real life saver for me, its my social life since my car is off the road and I live in a rural area, I market my computer repair business through it in the many local FB groups, etc etc.
The interface is just a FB share button to post memes on FB, but it links back to the site here, so I just download the ones I make and then upload them to FB it just makes it cleaner.
