Hi, author of Harrow/Capistrano here. Actually there's a video on the way, since we're still pre-alpha, so that people can see the (pretty rough) workflows. There's a reason we have't submitted the tool to HN ourselves yet. Yesterday we conducted some Tweet/Survey about Capistrano that we launched via @capistranorb yesterday, it looks like cnolden wanted to pick up some HN karma! Sorry that you saw (what I consider to be) a bit of a (technically) disappointing product landing page.
Nice to know that. I already signed for your mailchimp list. Hope things go well and have something ready for testing soon. It should be interesting project.
