Yeah, this is one of my Favourite Manga right now, I eagerly await the latest chapters every week and am absolutely hooked! The first Tankobon is out in the UK now (possibly the second by now too, I'm not sure!), pop down to Waterstones and pick it up as it is RAD, especially if you're a budding comic artist- it really feels like getting a fairly sincere look behind the scenes at Shonen Jump!
I've just finished reading the final volume of Ohba and Obata's previous collaboration, Death Note.
Yep, I'm a late comer to it but it's absolutely superb, it's made me a fan for life of both creators and I definitely plan to investigate their other works!
