A little math game
This is actually rather over my head, but it is kind of interesting. As I mentioned the other day, Livejournal Free Users get 0.99 syndication points. Subscribing to a feed that no-one else subscribes to costs one point, which is why Free Users can't add feeds to Livejournal's watch list.
As the number of subscribers goes up, the cost per subscriber goes down. For example, sebbofeed currently has six users (down one from before yesterday's RSS slipup) and costs 0.473 points. Here's some more data: the point costs of the most popular LJ feeds and a range of feeds with small subscriber bases. Your mission: to figure out what formula is used to derive the cost of subscribing. I gave up and Googled to this thread which in turn led to the definitive answer. I was a little disappointed--the math turns out to be too heavy for me to understand. I'm sure most of you guys can handle it, though.
UPDATE: Andre has charted the formula, complete with instructions on how to replicate his results.

I base these views partly on the success of a comparable approach to making models generally available in cognitive modeling (Google for "ACT-R cognitive architecture" for more details.) Good luck!

I haven't been up to anything , not that it matters. Basically nothing seems important, but I guess it doesn't bother me. Not much on my mind to speak of. Today was a loss, but maybe tomorrow.
