Why is it called a "Code Gallery" if there isn't actual code available? Is there going to be something equivalent to the old code gallery where you could sort, rate, comment, and download actual code?
Joshua, some entries have code available (for example the source code for the Flex Viewer). It is up to each developer if they want to include the source code (or not), or if they want to provide a working link to it (or not).
It is similar to the old code gallery in that you can sort, rate, comment and download actual code (if it was uploaded). Click on the "Details" below the thumbnail and you should be able rate, comment, and download the code (if available).
We decided to keep the name as "Code Gallery" because "Code and Application Gallery" seemed a bit long 🙂
