. . .I doubt that would be possible, none of us are Ron Burgundy after all.
Completely offtopic, but can you imagine Ron drawing manga?
Anyway, I think this is a neat idea, but as Loren says it would be very hard to cover everything/only the interesting topics. I mean, covering major/general stuff wouldn't be too hard, but there's some very niche series out there and someone may cover/not cover something because they feel it has a lot of fans/doesn't have many fans, only to discover the complete opposite. With that problem, it'll be difficult to generate huge amounts of interest, because certain people like certain things, and you're never going to have
everything up there - and if you do, other members will be annoyed that there's so much stuff there ('But I only want to know about Naruto and new Shonen Jump series'!'). The best scenario would be having a group of members who are interested in everything on the news, but that's unlikely. Good luck with it if you go ahead Vacant, but it's going to be a lot of hard work and will probably involve a lot of self-taste ('I don't think [insertserieshere] has a lot of fans. . .') or time-consuming polls ('Do you like Bakuman and want to hear about it in the news?'). . .
But go ahead if you want to dude!
