I love these specialty flow apps being built on the WordPress.com JSON REST API. An API is in the works for core WordPress. I’ve been cajoling people to build a “Hello Gallery”  webapp on both APIs that multi-select uploads straight into a gallery post with an optional title. That’s it. Anyone?
1: Like Hello Dolly, this is not just a WP webapp, it symbolizes the hope and enthusiasm of an entire generation . 😉
