For real. This is actually good advice.
"Just be yourself, bro" sounds like a cliché but it's true.
Back when I used the apps, I went with something like "Swipe left if you want normal, because I'm not normal. Here's what makes me a weirdo. If you're still reading by the end of it, maybe we won't waste each other's time."
It produced a way better experience than not doing that. I remember doing stuff like: writing part of the profile in iambic pentameter, and another part in Latin, going on about how interesting Persian poetry is, and listing stuff like "Arabian epigraphy" under "interests."
one of the biggest icks on dating apps are men modifying themselves in order to appeal to a greater number of women - by not expressing dealbreakers up front, by putting popular-among-women stuff in their profile, etc.
it's so unattractive it makes me viscerally recoil
