If you're a man who's not in top 10% of most desirable, it's a barren wasteland. Your best hope becomes to attempt to match with basically anyone, and even when you do match most won't respond. So maybe you tried to be witty the first several times and got no response or possibly unmatched. A lot of men will lose their wit after this and just start sending "Hey" in hopes of getting some kind of response.
Meanwhile if you're a woman, nearly anyone who you click 'like' will be a match (except for the few you really want). The men you'll match with may not be charming because they've become tired or desperate or jaded, some may be outright rude, sexist, or cruel, and maybe the guy you want isn't responding at all -- because he's in that 10% of guys that all of the women are trying to match with and he's ignoring you.
The upside of it being impersonal so you have more freedom to screw up without much effort or commitment is also it's downside, where the people you match with don't put much effort or commitment in for you either.
