I don't think it's completely awful - it's a matter of what you're comparing it to. If you're pitting it against a slick, non-technical consumer facing site, sure, it's a little text heavy. But if you're comparing it to a typical API doc, it's a pretty good combination of style and utility.
I don't think so either, but I certainly wouldn't mind lending a helping hand.
I find it somewhat hard to read and follow. Not really a problem with the design, more a problem with the layout, text size, and font.
Ignoring the kind offer, I would suggest that it is very well designed. As a tech consumer, I understood what it did from the name and sample calls in seconds.
Nice idea, btw. I was also thinking of something like this a while ago. Clearly there is a need.
I really like the current design, the only thing that bothers me a b bit, is that the "RunMeLater.com" logo is not aligned with the text on the left.
