I also met my Wife on IRC, ~20 years ago (after chatting for 2 years). Explaining then to people how we met was difficult, so we ended up just saying through a mutual friend - which was also true.

I strongly doubt it we would have met, in this day and age. The mainstream online socialising of today is superficial and desperate.

Today, a remote worker, I communicate with my colleagues over IRC. It's rare that I'd speak to a stranger on it.
