Honestly, I think you're doing an outstanding job here. A creative platform like this is exactly the kind of innovation to help Nokia get back on track on the software side of things.
I like how it's simple, down to the point, how it tells me what's new, and also where stuff I already have is updated. Exactly what I want from a Beta Labs Site that's supposed to provide me with tools normal folks will only get the day after tomorrow ;)
There should be more of that - try out stuff here, see how it works with the user crowd, skip it if it doesn't and focus on something else.
