I thought I would give it a whirl, So I down loaded the plugin and it worked right from the get go.
I am fairly new to Oauth and how the methods work. With this plugin being for WordPress, I would assume people would want to down it since they either don't want to develop their own or they don't know how and this is a quick solution. I would recommend adding what version of oAuth the plugin is also some documentation on how to use it. This would make this plugin a for sure hit since it is the only one that does it currently right out of the box.
