I'm not sure I'd say I particularly dislike OLD but it has it's foibles and unique challenges versus dating in real life.
In my case I have, or at least had, few other options due to being a single dad. Back in the day that was worse than leprosy in real life and particularly tricky when the kids were primary/pre-school age. Now, working from home and in a majorly male-dominated industry makes it tricky.
Even so, I'm 'good with women' face to face so had a couple of long relationships.
Online, there is way, way more choice but it's all about the photos and, while not ugly, I'm not classically handsome either so it's lots of messages for few replies (I get about a 60% response rate but I have friends who get less than one reply per hundred messages sent).
So, as I said, it's a different type of challenge.
In terms of weirdness, ghosting, intents, etc., etc. it's much the same as in real life, I just think people are more aware of the strangeness when they've met through a dating site.
