Yours is a completely delusional, onesided and fundamentally wrong point of view that isn't really going anywhere.
Yes getting a group and going there was part of the journey. Only lazies spammed chat and thank god they were rightfully ignored by most of the people.
Again, getting a group together (10-15 mins max at 10 pm in tbc) wasn't much of an issue for normal, polite people. Social awkwardness shouldn't be rewarded you know?
You never had to socialise in wow? Ah I see you must have been one of them. The ones that didn't say a single thing apart from "Rez pls" and were rightfully kicked and ignored. Yes for people like you lfd is a great success of course.
For normal people that cared about their character instead, having a good reputation server wise was as important as having good gear. It got you groups faster, a better chance to get into guilds and raids if you wanted to, and generally it made you feel good. Same reason why if in real life someone tells you "hi" you reply "hi". Same feeling.
Again, social awkwardness shouldn't be rewarded, it's no your fault you're born that way but it definitely isn't mine.
Edit: and yes I knew exactly who was reliable and who wasn't server wise. I know it might sound strange to you but people cared about the social aspect of wow when there was one.
Maybe that's why people avoided you?
