The Guardian Open Platform launches, with their Content API, their Data Store, and a selection of client libraries for the API (one of which I did a smidge of work on). This is not just a good thing, it's a good thing Done Right, and I'm looking forward to what's next from the Open Platform team.

"Our team of investigative journalists has compiled a database from four years' worth of company accounts to show how much the FTSE 100 companies make in pre-tax profits, and how much they pay in tax. We have published this data as a user-friendly interactive guide at guardian.co.uk/taxgap/data." But, as well as the user-friendly guide, there's also all the data. Bravo.
