I've personally never used reddit but have loads of friends who do. They use it more than anything else. They're always showing me stuff at work on reddit. I've mentioned steemit to no avail. Kinda baffles me but to each their own I suppose. As for ads..... as long as they're out of the way and not having me click them to remove them from being in my way I don't mind. It's when they become a nuisance to what I'm doing that I mind.
