I agree that it isn't a big deal, but often it leads to so many other questions, like which web site you met on and what you were doing there and all sorts of stuff like that. In our case, we met on Second Life which is a virtual world and kind of hard to explain to someone who has never been on there.
Yep. We were both members at Funtrivia, both the quiz part and forums. Things started going a bit haywire on there with some control freaks, so hubby decided to start his own forum. We were aware of each other but didn't interact much, but when he and the two people he started his forum with were looking for mods, a mutual online friend of ours from Canada suggested me, and within three months I'd become Admin. We all talked on MSN messenger and could find other admin or mods to talk to 24 hours a day with all the time zones, and after a few months he and I started having our own chat going without the others, and it took off from there. It is time consuming to explain all of that to people you will probably never speak to again, or rarely see. For those people I just say we were introduced by a mutual online friend. Some people also have to have the whole forum concept explained to them in addition to the rest of the story. I don't mind telling people who are or will be involved in my life the lengthy version.
It does feel weird to explain such an intimate detail at length with strangers. The way I see it, in past relationships I was rarely asked how we met because we were always from the same area, or at least the same state. Now, everyone wants to know, and some act as though they are entitled to know and press for more details than I want to give to a stranger.
