I'm resorting to peer pressure, extortion, and blackmail. Well, not the last two.
One of the people I am rediscovering again is Robert Cialdini, who is one of the great authors on the psychology of Influence. To see what I mean, do a search for

I am thinking of, as a pure experiment, using scarcity to motivate people to link to my site. I was thinking of asking for a link from their site in a matter of fact way, but then adding that, "I am only allowing 10 web sites to link to my site, so if you would like to be one of those 10 sites, then you had better hurry."
Maybe it will flop terribly, but there are lots of sites out there of questionable value, and it would probably only take me an hour total to email ten of them, so I might just try it.
My gut feeling is that I will need something more subtle though.
