Plead HN: Please build a startup glossary

An important and glaring problem is that it is very difficult for me to explain what I'm doing to my mom. Startup Lawyer has the start of a glossary (http://startuplawyer.com/startup-law-glossary) but a lot of the definitions are missing. In true Hacker News fashion, we should solve this with a webapp.

I'm thinking:

* A freeform glossary with basic, starting definitions filled in by a handful of trusted volunteers.

* Instead of simply being a wiki (which will lead to rampant spam), registered users can propose new terms and updated definitions to terms.

* Proposed changes (diffs) are listed under each definition and voted up/down, like Stack Overflow. Eventually proposed terms/changes are applied if they reach enough votes.

* Markdown and links to other sites are allowed, but links use rel=nofollow

* A good, SEO-able and paste-friendly URL structure, like startupglossary.io/convertible-note

* Open-source and hosted on Heroku, of course ;)
