Currently the main site I use for finding Cordova plugins is plugins.cordova.io. Last week Telerik announced the creation of a new site, the Verified Plugins Marketplace. This site contains plugins that have been tested to ensure they work well and contain sample apps written with Kendo UI. I've often said that as a new Node developer, the availability of npm modules is both good and overwhelming as well. Having a curated, filtered list of plugins could be a huge benefit for Cordova/PhoneGap developers.
