Given the number short-lived web apps that appear and disappear, the about us page is becoming one of the most important. Any "about us" that doesn't mention people is an immediate close for me.
It doesn't matter if you're a one-man band, put up a picture and work out what details of your life so far will cause people to trust you.
The question I ask my self when I visit a web app is "Why should I give you my information and what will you do with it?
Expect an "About the Invoice Ninja Team" page soon.
For now... here's a link to my blog http://hillelcoren.com/. I've been building apps for a while now and stand 100% behind anything I create. This project is team affair though.
I realize trust is earned and I hope we're given the chance to earn it.
Edit: added 'to' (grammar mistakes kill me)
For some more substance: I quite like your tool, but I wish the preview was more instant and not a pdf. Perhaps you could render your pdf previews to an image, and only provide the pdf when download is clicked?
Also, apologies if I missed it, but is there a way to customize the template, or will this eventually be possible?
