Thanks for the criticism...copywriting isn't my strong suit. In my defense I think the site makes sense if you're a teacher. At least that's what my wife (the teacher) tells me :)
Your wife has some associated bias. I totally agree with them, you can increase your revenue like 5 times if you just made that clearer.
But I guess you have some point since I'm guessing that the Edu website gets noticed not because of Web search but word of mouth of teachers. And probably the teachers who spread this website to other teachers have well explained the product's features enough already.
But If you just upgrade the clarity of your site. The web searcher won't get trouble and know your site's purpose immediately.
I have to say I admire your productivity. Bob Walsh (47hats.com) has an eBook called "Micro ISV Sites that Sell" that's gotten some good reviews that you may want to have a look at. Good luck with the sites!
