I'm very much interested in covering business applications of Second Life and OpenSim, for both in-world and real world uses. Generally speaking I prefer stories on broader business implications and economic trends, but if a particular company is uniquely innovative or successful with their SL operation, then I'm particularly interested in writing about them. With coverage of real world companies using Second Life, I'm even more interested when they're using SL to benefit the existing community -- as was the case with Amazon's recent in-world job fair. NWN editorial coverage of business was definitely different during SL's first hype period phase of 2006-2007, when I got buried in press releases with variations of "X big company is the first Y type business in Second Life!", few of which amounted to much. Since then, however, it's generally safe to say the companies that have stayed after the hype waned are serious about the platform, and the community.
All that said, what uniquely innovative business applications should I be keeping an eye on, nowadays?
