Google held a GTUG (Google Technology User Group) meeting in London earlier this week, where they announced that they’ll be building a marketplace for apps.

According to Lars Rasmussen: “We’ll almost certainly build a store…So many developers have asked us to build a marketplace—and we might do a revenue-sharing arrangement.”

This makes sense.  Even with only a few extensions available in the Wave “Extension Settings” wave, it’s a bit unwieldy.  Having a proper place to search, sort and sell them will make a lot more sense.

It’s certainly still a long way off — there’s still much work to be done on the core framework.  Still, it’s an exciting concept to look forward to.
