There have been quite a few comments to various of my blog entries, all covering the competition, so rather than try to answer them all individually I'll try to cover them here:
1) People have mentioned that while they saw London Underground on stage, they didn't see any other customers in the videos. Well, they absolutely are there. In fact we had 5 customers in various videos throughout the day, however the questions don't name all of them. So you need to make a note of the customer names, then see which ones appear in the list of possible answers, and select them.
2) Some people were hoping for technical questions rather than "which customers". We felt a technical question would be unfair to newcomers and to developers from competitive platforms. This approach requires you to watch the video (you won't really be able to guess unless you've watched them) and doesn't differentiate on the basis of technical knowledge or experience.
3) Some people felt that none of the customers actually appear in the videos. At least one person said that there were "no customers on stage during any of the Vista sessions". Well, that's not true. All of these customers absolutely do appear, and customers are in both the Office and Vista tracks. I have just watched the appropriate videos myself and yes they are there.
4) Some people have said "surely you don't need us to watch all of the videos before we'll get the answers?". If you want to take part in the Office competition, you'll need to watch the Office videos; And if you want to take part in the Vista competition, you'll need to watch the Vista videos. And if you want both, you'll need to watch them all. Of course, you can use the "thumbnails" to skip to the part of each video that might help you.
5) People have asked if the competition is already closed. No, it runs until 19th February. See http://www.microsoft.com/uk/launch2007/dev/vistatoc.mspx for terms and conditions.
I hope that helps to clarify things. I know it means you have to watch quite a few videos but to be honest that's the point.
