I read a tweet by Brendan Maclean on the same sex marriage bill that was in the Australian Parliament, and I realised he was right. So I built The 98 Against (and it's sibling, The 41 Against) as a response.
By screen scraping the Parliamentary website, I was able to provide a single place to contact all of the appropriate parliamentary members who voted against the bill. Armchair activism ahoy!
Esperanto Magazine interviewed me about it and everything.
