Awesome lesson, and I appreciate that you explained the implementation.

We already have too many apps shoved down our throats. Make it as seamless as possible for your app to work with the tools people are already using (i.e., don't send emails that say "You have a new message at NewApp - click on this link to see it" - actually SHOW the message) and you'll have much better adoption.

In the same vein, add an option to reply to the email to add a reply or comment to the message.

I'm pretty sure Brad already implemented that. At least you can do that with the Basecamp part of Revisu. But it's on the list.

Sorry, I meant for web apps in general, not Revisu specifically.

This is a message that more of us could stand to hear.
