With regard to "It's kinda hard to see the advantages of a one off system like this in that context."
We see this as a major advantage. Most current systems provide (at best) mediocre solutions to the problems their users face. Instead of doing everything and having it all be mediocre, we took a single problem teachers have and solved it the best way we could.
I see that to a point: but a teacher always wants 100% the easiest path. If their "generate pupil report" button (guaranteed to be their #1 gripe writing reports :D you should here my mum are report time!) requires them to have used the inbuilt school system to set assignments then they will just use that - no matter how much better your way is (dont get me wrong, I think it's damn good - I wish we had had this kind of thing!)
I think my main point was that it is a 8great* way to approach this problem - but it needs a bit more on top of it to really sell it to a mass audience (IMO).
I could well be wrong, I have been many time before :)
Thanks for the feedback. We're trying hard to get all perspectives on this issue since we know we're tackling two major problems at once: designing an awesome web app and competing in an entrenched industry.
Again, the feedback is really appreciated, if you think of anything else be sure to let us know (founders@classlet.com)
