Okay first off, OpenStudy came out first. That existed and annoyed people because it was very buggy, but people liked using it and sometimes wasted their money on it as well. Then about 5 years later (this year) the guys decided to close it and make Brainly, the huge new thing. I hated that because it cost points to ask a question that rarely got answered, and even if they did, sometimes it was wrong or not helpful at all. I got used to it, and I was fine until now.
They decided to add subscriptions for, wait for it, $15 a month. Overkill; it made Brainly just like all the other websites. The problem with subscriptions is you can't view "verified" answers. Verified answers are normally 100% right, however, there is a 5% chance of them being wrong. That's pretty much all, it's good unless the help you're looking for is verified, unless you want to waste 15 bucks a month.
Don't use Brainly; Peeranswer.com works just as well.
Bottom Line: No, I would not recommend this to a friend
True, peeranswer.com does work but it takes a while to load.
