I did find the source for the error you ran into and pushed a fix just now, by the way — it was nothing having to do with .NET, it was just a string comparison that didn’t take into account the fact that anyone would ever want to create a three-character document. Fixed now.

As for Writely – by saying “more evolved”, I meant that it does also allow users to share documents in a similar manner Approver does. You can either just share a document with a group of people or you can invite individuals to collaborate. It also logs all document revisions by collaborators. Like I said, I do really like how Approver is set-up because of its simplicity. I think its simplicity and ease of use will definitely be one of its strong selling points. I also really liked the guided tour. Its a great way to let users know exactly whats inside. I am sure you will hear lots of good things about Approver from the blogging community. I am involved with a startup also so I know how good it feels to get noticed.

Thanks for the review. I’m having a look at the error you ran into — it looks like this might be something unique to you (no one has run into this problem before). It’s possible that you tickled something new that we introduced in our last production push on Saturday — I’ll have a look and let you know what happened.

I’d be interested to hear more about why you think Writely is “more evolved” — they have a better in-browser word processor, but that isn’t the problem that Approver has set out to solve. We actually don’t look at Writely as competitive with Approver at any rate — they’re trying to give people a free alternative to Word and we’re trying to give people an alternative to sending documents around in email.
