I've written most of the plugins and take responsibility for their strengths and weaknesses. Nick Niemeir pushed us towards the node.js/browserify conventions. Paul Rodwell reorganized the plugin repositories.
I wrote Federated Wiki while I served as Nike's open-data fellow. I currently work for NewRelic in Portland, Oregon.
Correspondence
I often correspond with authors writing their first plugins. The sequence of issues that surface are characteristic of the the learning curve and worthy of review. I will cite them here when these conversations happen in public.
