I decided to take on the challenge to build 30 things in 30 days with VanillaJS. No frameworks, no builds, no boilerplates, no libraries. Pure ES2015 goodness and Codepen.
Better Follow Button for JetPack (BFBJ)
As a tribute to the original "Follow Button for JetPack" plugin, I've decided to pick up the tab and continue development of this extremely useful plugin that brings out native WordPress ability to subscribe your readers to a mailing list. The original plugin has rigid and not customizable. BFBJ project will continue improving and adding customization options to the follow button plugin to allow blog owners to style the look and feel of the plugin to match their site. You can learn more about this project here.
I have since moved on from WordPress and this plugin is currently not maintained.
