It looks pretty, the example looks pretty slick, but, it's not all that easy to use in a hurry, and I'm not even sure history exists<p>It shows a very good 'State of the Machine' at the current moment in time, but it does feel slightly like candy<p>One major, major thing I would add to convert this into something I would use for my 'strtup' is time, and the ability to see what happened at a time, or event<p>I am basing this on the 'live demo', but it seems like a report on what's happening now, which isn't really that useful in the grand scheme of things. For instance, if I drop a new feature or blog post on HN, I want to see what effect that will have on my application, and what users do and where they go after first opening that email or clicking on that link<p>This may seem insane, but I promise I am going somewhere. In my GCSE Physics exam, we were given energy diagrams, and told to do things with them like fill in the blanks. On the left, there was a kind of 'origin', which represented the energy given out by an object. So say a lightbulb gives out 80% light, and 20% heat energy, that would be represented by a 10cm wide arrow on the left hand side, which then breaks into a 8cm wide arrow pointing right, and a 2cm wide arrow breaking off from the main chunk and pointing downwards, to represent waste energy.<p>This loops back into analysis, say when Flow was first posted onto HN. You could break that down into signups, showing where people dropped off, what pages they viewed and where they went from there, and then render that in a pretty diagram, hopefully showing you where the friction points are<p>I do also have two minor issues I picked up on from Flow, and I suppose Mixpanel<p>Given it's a free product, which may or may not have the aim of pushing users into Mixpanl, I could not find any obvious links to <a href="https://mixpanel.com" rel="nofollow">https://mixpanel.com</a> on the main page. Which was kind of sad, I wanted to read more about Mixpanel and what the bread-making product does, and how it sustains this free app<p>Secondly, I emailed Mixpanel back in January asking about details for an internship. Since then, I have received a grand total of nothing from them. Which is sad, metrics and user statistics are two things I thoroughly enjoy, and I would love to work with Mixpanel to build things like this
