This is probably 'good enough' (and certainly is beautiful) for people not currently using anything for project management, but probably most of the HN audience already has something that's working somewhat for what they're trying to do now, and you're trying to supplant that.
There's almost no amount of screenshots that are going to get me to give up on the devil I know, so at the very least a product tour that shows interactivity is needed. Better than that would be a free trial, where I can get in there and try out some scenarios and compare them to the pain points I already have with my existing tools.
Like I said though, it really does look great. Fantastic even. But without being able to click on anything, I don't know that it isn't just pretty.
