Curious, how many people do you need on a social network before you can find someone to talk to or before it is engaging enough for you?

I certainly don't need a billion users. I think I'd be happy with 100,000 users -- what is your number?

I think this is related to the question of how big of a city do you need to live in before you can find something to do and are not bored living there. I'm fine with a city of, say, 50,000-100,000. That is more than sufficient for me to find an appropriate number of likeminded friends and neighbors as well as interesting pursuits.

I don't think that's a meaningful parameter to think about? I'd say that on any social network, I have meaningful, ongoing relationship with maybe 20 people. I suspect that's the norm. But that doesn't mean you can join a social network with 20 users and get that. I mean, if it's a mailing list for friends and family, sure. But not if it's 20 randomly-selected strangers from around the world.

So the critical mass to make the "random stranger" type of a social network work is much, much higher than the number of daily interactions you need to keep coming back.
