Observations about tinder

Most people (at least in my proximity) who writes in their bios that they are looking for something serious have horrible tinder profiles.
They are the ones who pick the least flattering photos to upload. They look tired or messy or depressed or upload goofy photos from which it is nearly impossible to tell what they actually look like.
If they are so serious about finding a partner then why don't they put in effort to their profile? There is no need for supermodel posed photos but photos where one looks friendly and open and where you can clearly see someones face are necessary. I, myself prefer to meet someone in person and hate the shallowness of tinder and in the end I always pick the person I feel I have the best chemistry with. I've rarely picked the most attractive guys in my matches to go out with but rather the most funny or friendly and intelligent ones.
Tinder is still about first impressions and I think one should attempt to make a good one. It's like how you make sure to look nice on a first date... you dont necessarily need to dress fancy (unless you're doing something fancy) but one should look nice for the sake of putting in effort.
Another observation i've made is the guys who complain in their bios about how no one writes first or talks to them after matching and other negative comments. So the first impression they're choosing to provide is showing how bitter they are.
I am a woman who doesnt mind texting first but when someone has that kind of attitude I consider it a red flag. Too much negativity.
Yesterday I came across a real frustrating profile of that kind, a guy whos entire bio was dedicated to complaining.
He complained about women who doesnt text first and who arent social enough for his taste and then "dont text me hi because thats not good enough and I will unmatch" and thats where I stopped reading and swiped left. The bio was loong... and full of pettiness. Tinder is so much fun to read sometimes. xD
