Looks like v1 is officially being retired in May. As it stands, this plugin will no longer work once they fully retire v1. I am playing with ideas to update this plugin so that it works with v1.1 but also remains simple for end users. I'd really like to find a way around using oAuth because it is a pain in the butt for something simple like this.
I might switch to using the search API but here are some potential downsides:
I'll create a test version of using the search API and see how it goes on my site, then judge from there. Considering there are over 1000 downloads but no reviews I'd assume not many people are still using this anyways.
As always, feed back is more than welcome.
