Well, you have to be willing to work for cheap (i.e. free) and have at least a passing knowledge of Eberron (stonegod is really the go to guy on the setting, my typical one is FR). stonegod decided to reboot LEB for 4e when there were 0 active games and no new prospects. I like 4e and wanted to help him get it off the ground, also I like being able to help out some of the newcomers. I sent stonegod a PM when everything was being worked out (the new charter there) and he said yes.
Personally, I like it. I'm actually enjoying reviewing the character sheets and seeing the different PC's people put together. It's also nice to have a say in approving different proposals and stuff. If you like 4e and want to try a game above 1st level it's a pretty good option. There's less risk of DM disappearance as the Judge (me, gulp!) would step in if a DM abandoned mid-game.
