I created many webservices in C# under .NET, but switched to WordPress last year. My goal is to provide WordPress teaching, consulting and development services to WordPress developers. This plugin opens huge opportunities for me to show other WordPress developers how to make better sites.
I am very impressed with the quality of the code and documentation and have many ideas for how to implement this in my own sites.
Color me excited and very happy! THANKS!
5/1/2015 Update: I am almost finished with a massive plugin called PostLister that uses JSON API to load all posts into local storage. I am so delighted with the JSON API code that I am looking forward to doing more, as soon as I can release PostLister.
