Workflowy people: Please please please provide an API. I like your tool, but 99% of the time I'm doing something I need to make a todo, I need to do it somewhere other than looking at your web page. For example, from within vim. Or at the command line. Or while checking email. A nice API would allow me to whip up tools that make it super easy to access from wherever.
We do want to make an API, but we think it would be irresponsible based on our current organizational status. We're still in scrappy-two-person-startup mode, and we don't want to do the poorly supported, unstable API thing.
Other than that, very nice tool :)
