Here's a pretty good article on Raijin Comics Weekly. The article gets a few things wrong though. Raijin Comics Weekly is not the first Japanese manga to be translated to english (though it (or Shonen Jump) may be the first comic in this format to be translated)). It is amazing how much the manga market has grown in the last year though. The number of titles being translated is growing rapidly.
Personally I'm enjoying both Shonen Jump and Raijin. And as far as other titles I'm enjoying Marmalade Boy, Kare Kano, and Chobits quite a bit.
