I really appreciate hearing your perspective on all this! Lots of good points that I will consider. The convenience factor and lowering the barrier of entry is definitely what I thought would have some appeal. Use in various education settings included. Edit: one thing that I realize now is not clear at all -- anyone with a Google account can use it to login (no password) if you visit the "sign in" page instead of "sign up". I need to make this more clear. It's definitely apparent now that having a way to see how it works without having to login would be a great improvement. I'd considered it before but haven't gotten to it yet since the implementation will be some work. I'll reevaluate. And thanks for the other tips.
