Tried it after my second divorce (you can see I’m pretty good at this relationshipping, eh?) and it was awful. One date basically interviewed me for “next wife and mother” position. I wish I was kidding. The rest was just a barrage of dick pics and come ons. #singleforlife
The downsides: Uh, well, not a lot of people know about it. Though its download rate has been picking up rapidly over the past year, it's gonna be a little difficult to find mutual haters who are actually near you. I'm in the United States, and most of my matches were from Europe — which is fine if you're just looking to bitch about the same thing together, but not awesome if you're trying to start a legitimate relationship. (Give it time, though. I believe in this.) There's no desktop version (most modern apps will skip that), but the smartphone app is really hip and slick.
The bottom line: If you're a gay man, an app that's specifically for you is your place to shine. There are obviously gay men on Tinder, Match, and many other dating apps, but that's probably their backup app, and you're likely to circle through the same batch. No one wastes time on here, and if you're in the mood and looking for someone ASAP, Grindr won't steer you wrong. Just don't expect to meet your date's parents any time soon.
