This is a great idea but we would really need to build several new pages ideally with links to the API sandbox, code samples. This is a big project in itself. The landing page should be close to something like Flickr [1] and should detail why someone would want to be a developer, the sort of things they can develop and with what skill set and should give a brief but interesting overview of apps/sites that use the API or extend mediawiki in drastic ways. Part of said page should be about inspiring people to develop with us rather than elsewhere.
I'm happy to use my 20% time to work on this with people. Just give me a shout offlist.
It should definitely link to the Annoying little bugs page as well. It contains a decent selection of bugs that new developers can fix.
Not 100% sure the scope of this page though. Was it meant to attract just extension, gadget, et. al developers? Or was it also meant to attract developers for the core as well?
Thank you, Derric Atzrott
