Why is this exactly, and does 250 apply equally to all players?
Isn't this really a question of the statistical deviation of a players skill rating, with a lower deviation for consistent players?
In sc2 the skill of players can change very rapidly, and vary a lot. I don't know how well this system accounts for that, but I do believe the statistical deviation for each player is an essential statistic in addition to their ranking.

It doesn't apply equally to all players, it's a rule of thumb based on the mean deviation observed across the player pool. Even though the deviations change a bit, it doesn't impact this number very much, so for all practical purposes you can consider it to be constant.

Do Koreans still start at 1200 and offline is worth 1.5 times online?
I also noticed Mvp's spike early 2011 is lower and is thereby no longer in the all-time top 5--was this from an individual change in his results or an overall change?
Thirdly I saw that foreigners jumped up a bit in the HoF -- changes there?

- Yes, you can see the parameters in the github repository (rating numbers are scaled by 1000 and shifted by 1, so 1000 displayed on the site is 0 in the code).
- We lowered initial uncertainty a bit. (Same file, you can read the history. Note that this might include changes that were never pushed to the server.)
- Could also be related to #2. It's the only thing I can think of.
