Hey there!
Cesar has recruited me to give you the developer's perspective here on Zune Insider. I'm a program manager on the Zune Social team, and I also spend a good amount of time in the forums, getting users' perspectives on features we have already developed and what you'd like to see in the future.
So what's a program manager? Basically, my job is to figure out the details of what the development team is going to build. Program managers have a foot in two worlds: we have to understand both the needs of our business, and the technology we'll use to build features. Pretty much it's the best job around here. :-)
I'll be hanging out and blogging about a couple of things. I'll talk about how features that already exist came to be, in an attempt to give you some more transparency around our process. I'd also like to have conversations with you around feature areas I'm thinking about - I won't be able to tell you what exactly we're doing and when, but I will talk about how I see various aspects of Zune Social and engage you in those discussions.
Feel free to add me as friend, by the way - I listen primarily to electronic music and look for new stuff (well, new to me) every week. Plus you'll get the added bonus of being able to see every time I post in the forums - woo hoo!
