daytum
I’m digging Daytum, the site from Ryan Case and Nicholas Felton “for collecting and communicating your daily data.” The UI is a bit inscrutable at first – you have to want to use it – but once you understand it you want to experiment. The data capture mechanism – and the underlying data model – is flexible enough to support multiple viz’s of the same data set, which should be fun…as long as I can figure out something more interesting to track than number of cups of coffee imbibed and number of hours slept. (Feature request – ability to layer one data set on top of another…)
