Journal Games

[trouble]

I've got a hankerin' to run a game again. (I'm hoping it goes away. The scars from the last Mage LARP I ran are still raw.)

I was thinking of running one via a journal-service, probably DW, but maybe LJ.

How does one run such games? How do you get players? How effective are they? Do they have a lot of staying power, or peter out after a few weeks? How does time work in them?

Any thoughts, opinions, or advice?
