I'm a bootstrapper looking to build a profitable business, not someone chasing an acquisition or an IPO.
Ending up with 1000 users who aren't paying me is no better than where I am now, is it?
Once you have a 1000 people hooked on it, I have no doubts that you could think of a premium feature that opens new features to these users that they'd be willing to pay for. Again its about getting those users and showing them the benefits first.
A related problem is, on watching your presentation, I don't think you solve a problem teachers actually have. No teacher gets up in the morning and goes "Dang, but for my crushing lack of simple data tools, I'd be ready for today."
In another comment, I wrote this about Bingo Card Creator vs. Knack: I think the difference is that he's providing something teachers already use, need, and look for, as opposed to a "new" kind of software solution. (Online gradebooks aren't that new, but they still are not in use by the majority of teachers.)
I really wonder if the difference is just in what we're selling. If I understand your product correctly, you offer instructional materials teachers have been using for a long time: customized cards to play bingo. This is something teachers are familiar with. As I mentioned in the post, teachers already buy classroom materials like pencils, letter charts, and decorations. They've been buying these for years and actually enjoy buying them. Bingo cards are a familiar need and expense. However teachers do not, generally speaking, regularly use software, much less pay for it every month. The concept of paying for an online gradebook is foreign, regardless of what the software looks like.
If you don't mind, I'll send you an email to follow up. I'd really like to continue discussing.

Maybe I didn't hit on this hard enough in the blog post—teachers just are not a ripe audience for software in general.
