As someone who is hosting a few petitions, I also want to point out some other interesting petitions I have signed. Municipally I have signed a Green Budget Petition, and provincially I signed the "One Public School System for Ontario" Petition.
The Ottawa-Municipal budget petition is an online petition. I don't know how much value these have, unless they are also being turned into an e-mail letter writing campaign. Politicians don't tend to give online petitions any credibility as the online culture makes forging names/etc much more prevalent than is the case for offline paper petitions. This isn't a technological difference (paper petitions are easy to forge signatures), but a cultural one.
