Much has been debated about the value of digital property and user-creation. Terra Nova has also previously focused on how user creation can extend to the real world. Quality of user creation has also been as issue. It was with those issues in mind that I am so jazzed about SLExchange and the quality of the Saedaku Flamebringer, Saedaku Tactical Folding Knife and (of course) the Seburu Compact-eXploder. The Flamebringer in particular is interesting, as it is being developed for Unreal SL, Bedazzle's attempt to create an FPS within Second Life. PixelDolls and VERTU have also started selling content as well.
Much like Gaming Open Market, SLExchange does a great job of integrating into Second Life and makes it easy for users to shop when they aren't online or don't have a lot of time. I think that it will be very interesting to watch SLExchange's expansion over the coming weeks and months.
