As a preface, I've generally been a proponent of interpreting the scope of our site relatively strictly, and keeping it fairly narrow so that it doesn't lose focus from the intended goal (Android). Gadgets, I feel, ended up shutting down for a reason, and I don't want us to turn into Gadgets 2.0.
With that in mind, I think we should accept questions about Glass.
It runs Android. Although it's not using quite the same Android that other devices run, neither is Google TV, or the Galaxy Gear or even things like the Kindle Fire. As long as the questions are within the other bounds of our scope (non-development, not a shopping/purchasing question, etc), I don't really see a reason to exclude them, personally.
Now, granted, there is a significantly smaller set of people around who could answer Glass questions with any kind of authority at the moment. However, I don't think we should let that alone dissuade us. Hopefully we'll be able to attract some Glass experts over time.
Also, I suppose at some point we may need to deal with the fact that there is a Google Glass proposal on Area 51. It's only in the commitment phase, though, so if we decide to allow questions about Glass here then we could likely subsume it.
