The landing page is kind of slick and vacuous, with cute little images. That feels like marketing did it, not engineers. Perhaps that's unfair but it's a bad sign for me.

"Dark-Mode first / because your eyes are worth it" That's not based on any evidence, just what you want to give. It's not a selling point for me. I guess you allow it to be changed so I guess it's not a problem either.

https://trueq.io/create-question, well literally you can't even fill in fields - as in, type in text - without javascript enabled. That alone will kill it for me.

Also how does it compare to SO?

Just some feedback - good luck!
