The system, with its highlighted words, is great. 5 stars.
The feed needs fixed, it's just a bunch of random articles. I can't find my own uploaded content half the time, even under Imports, without searching specifically by name. 4 stars.
The forums are toxic - there's a 85% male ratio on there, I'd estimate. Questioners are a mix of internationals, and "bros" who use their words-learned as a way to measure themselves. I thought the forums had a bit of toxicity to them, then I got straight up attacked by someone I had never talked to. Another time, spam was posted in a forum, and I called the person out on it, and a group swarm came after me. They also accused me of "group think" while they swarmed, without ideas/original thoughts backing up their opinions, just insults. The spam they posted had a gender-dynamic to it; trying to convert men (and men only).
I don't know if Steve's looked at the user data, or even cares, but I'd bet he's pushing away women users from his site. I'm someone comfortable swinging it with the guys, and dang, do I not want to be on those forums. Within 7 days of starting my membership, I was being bullied [and by someone who thought I was a man, since he called me a "little boy."] The fact that very few women ever speak on the forums is an extra sign that this app has cultivated a bad chat culture that is (likely) driving away female potential users.
