The Law of Supply and Demand
The blog is still in its infancy. I experience genuine surprise when one person reads it and feels compelled to comment. Imagine how surprised I was when I got four comments asking me for Joost invitations after I published a post about it.
I think that the strategy being used to introduce Joost is a very good one. I don’t want to rub it in or anything, but Joost is working quite well. I think the smoothness might be enhanced by the relatively small number of users. If they had simply allowed everyone to get on the beta version, it might be an entirely different picture, and that would be bad for word of mouth promotion.
The other aspect that makes the trickle of invites seem like pure genius is the fact that scarcity creates demand. This is going to be a temporary effect, because I believe the supply is increasing exponentially, like the in old shampoo commercial.
