pimpmonkey2382.313: Petitions won't work...but wishlisting might have a better chance.
Not necessarily.
When a petition garners enough signatures, enough being even as little as a few hundred signers depending on the place and the cause, it does get noticed, and can have an influence in making a change.
However, before lending your voice to a petition, read and research it, as you must be sure about what that petitions says, and who it is that is sponsoring the petition (presenting and influence organizing).
Petitions are a collective voice. So few people engage politics and business interests to complain or try to change bad policy, in this age, and this is one way that you can reach people who are operating in exclusive circles and other various bubbles. Maybe nothing gets done, but at least you have made your concerns and complaints known to them through a public notice.
