I just signed into Tumblr for the first time in several years....it looks totally different! I'm not sure when these changes happened but the logged-in page looks much more like Twitter now. Back in 2015 or so when I used it semi-regularly; it was much more confusing then compared to FB/Twitter. You could reblog and like, but not comment. It wasn't clear at all whether commenting was even allowed, even though I'd frequently see posts with a chain of comments. It looks much more straightforward now.
