Looks like everyone needs a healthy developer ecosystem these days (except Skype). Yesterday, Vivek Kundra, CIO of the US Govt announced their very own AppStore for government cloud services, called Apps.gov.
Coverage here in the New York Times, and in Mr Kundra's own blog post.
Reminded me of a developer program we had specified and costed for the UK Govt. in considerable detail quite some years ago. We'd even started to feel optimistic about it proceeding, but then the government chose to invade Iraq and overnight all discretionary budget was redirected to bullets and bombs, not software.
