Who owns Wikipedia? by Seth Godin. Too good too pass up!
The question: why are they there?
I haven’t talked to Jimmy about this, but here’s my guess, one that applies to other community-funded efforts: If the user supports it, she owns it. If support comes from anonymous government money, or some corporate sponsorship, then the interactions don’t matter so much, and it’s more distant from you.
I would bet than any charity or cause that gets involvement from its supporters (and I believe that volunteer support is worth more than cash) outperforms equally well-funded organizations that don’t have as deep a connection.
In other words, you own Wikipedia.
