Gromunity is a working prototype of an online community for urban gardens, in a form of a local market for selling, borrowing, and trading produce, tools, and manpower. We made for the first Cleanweb Hackathon in San Francisco. The site is mostly functional but inactive: we weren't able to market it successfully after the hackathon.

I've always been annoyed by incorrect pluralization in websites ("1 events", etc), so I developed pluralizer, a Yii widget that correctly pluralizes labels for dynamic data. Usage is simple: an instance of the widget is created with the singular and plural forms specified for all labels, and a JavaScript function must be called whenever data changes to refresh the labels.

I wrote a short article (if a Facebook note can be called an article) about pluralizer here.

CitySandbox was a platform for residents of the Bay Area to ask questions and voice concerns about their communities. Users could post questions on the map in a sort of Reddit / Stack Overflow / Google Maps mashup, and the site could even generate mini-flyers with QR codes for questions and events. CitySandbox is unfortunately no longer active, but you can read about it here.
