I had the same reaction. I think if he just spent some time in creating a clear message and then putting that message on the front page he might see an increase in users. If you think about the average user they need to have the selling point made a clear as possible, more so if we're talking about the average teacher ;^).
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!
I want to echo this as well, because I feel exactly the same - and because I left a comment on Matt's site saying i thought planbook could be MUCH more profitable, but I didn't go into elaborating on HOW it could be. gcheong nailed it.
It's a calendar? With only all-day events allowed? And with TinyMCE?
What am I missing?
