Nice! Hopefully they will use this to become more open. Right now all you get is a map and some small API stuff. No free/open licenses anywhere.

(Full disclosure: I run an open project, PressureNet, that WeatherSignal competes with in the crowdsourced weather data space)
And we're working on making our data more open - with our new resources we'll have more time to work on improve the data we make available via both our website and API.
