Armchair conclusion: false. Introverts are more likely to use online dating sites and engage down other avenues that would not be natural, but rather virtual.

I don't know many of my jock friends growing up that had a "girlfriend" in an MMO, as an example.

Those things are not at all alike. Bartending means accidental social interaction; using an online dating site is deliberate. If you're in a relationship and using an online dating site, the relationship is probably already deeply on the rocks. If you're a bartender, you're more likely to accidentally meet someone you click with without even trying, which might imperil a relationship that's doing pretty well.

Armchair conclusion: false. As an introvert even online interaction with people can be exhausting.

Virtual socialization is more of a shy extrovert thing. An introvert will get exhausted after a lot of socialization, virtual or physical.

Online dating sounds incredibly high socialization to me. You scan through dozens of people in quick succession and interact with many of them. Talking to a single stranger in real life is way less demanding than that.

You're right to distinguish shyness from extroversion; as someone who became less shy without becoming any less introverted, it's not a clear association.
