Thanks for the feedback. Education is for sure an underserved market. One of the reason is the high barrier to entry. It's a completely different ballgame when you're selling to schools rather than small businesses.
Having a bundled lesson plan, multimedia attachments, and links to resources is definitely something we want to look into. Our goal is to have the teacher eventually teach from his or her Planboard. We're still far away from the digital classroom but we believe the next big change will happen in education.
Shortly after launch of our own app, we created a marketing table in our database. One metric we implemented immediately is to find out where users are coming from. Later on, as an example, you can join that with your user table and know where the paid users initially came from.
We also tracked how many times user logs in per day. From that, we started tracking many of the actions within our app. Now, using another table, we log almost all of the user's actions to get a better idea of how the user is flowing through the application. At the end of the day, track what you think will be useful to you and don't be afraid to track more than necessary.
Use a read later service like Instapaper. You wouldn't want to be reading HN all day because that would just be counter productive. At some point, you have to ignore what's going on and get back to work.
While you struggle with design, I struggle with code since I'm more of a designer. It's even worse because all I can do is stare at a static HTML version and imagine the functionality of my app!
