Earlier quoted context omitted.
I disagree that the qualities one wants in a long term relationship are not obvious with quite short interaction. It's not mere superficiality. You can suss out a person's character very quickly. Instincts are usually right.
Tell that to everyone who's been in a relationship for 6 months before breaking up because "he/she seemed so perfect when I met them"
That's because people misrepresent themselves online and offline. Reminds me of the Chris Rock quote:
"When you meet somebody for the first time, you're not meeting them. You're meeting their representative."
