Well - maybe you're more successful IRL not because you leave a worse impression online but due to the barriers to actually following through on message exchanges that I was talking about earlier. (I refer to it as "the hump": Someone asks themselves, 'Do I actually want to go over the hump of meeting this person and putting my time/energy into this?')

When you meet someone organically, they already have so much more information about you - if you click, what you actually look like, how intelligent/funny/whatever you are, etc - so there's no 'hump.' They already kinda know if it's worth it or not.

Dating has changed, for sure - but I find it's changed along with the way society has generally changed, so you'll figure it out. I'm generalizing but people kind of have a worse attention span, are flooded with abstract choices, are distracted and maybe less centered. It parallels the way people generally behave in day to day life. I'd say keep on giving it a go but realize its limitations, and don't let it be your only source of meeting women.
