If you're trying to get a community to take action, make sure the action is something members will enjoy.
Telling members to sign petitions, write letters to their politicians, stand in the cold and shout at people entering shops aren't tactics people will enjoy.
It's hard to get people to take action, if the action is something we don't want to do.
You can ask members to give you feedback, or you can ask them to tell you the one thing they dislike about your products. You can ask them to pretend they're the CEO, what would they change on their first day?
If you give it a little thought, you can make almost any tactic more enjoyable.
The best actions are the ones that you members will enjoy.
