My Idea:
An e-marathon.
In order to get new featherheads, it has to be something that anyone can participate in without having to jump through hoops. The more complex or demanding the contest, the less likely the average internet-goer will actually care enough to participate. I’ll jot down some random events that must be accomplished to win, but these will just be ideas for thought:
All the legs of the race are kept secret until the day of the contest launch. But there will be plenty of advertising beforehand so we have a bunch of people ready to go.
On the day the contest begins, the first leg of the race will be to post in a thread X (this gets more users to register to the forum, and rewards those who already have an account and can insta-post)
Leg 2: Create an FTC wallet (this also will benefit contributing members who already have an account here. Perhaps post the address in the aforementioned thread X)
Leg 3: Make a pro-FTC tweet/facebook status and screenshot it
Leg 4: Similar to what kagemusha posted, you have to take a picture of a feathercoin logo you put up in a public place where it would be reasonable that X # of people will see it per day.
Leg 5: Tattoo FTC on your neck
Leg 6: make a thread with proof of you completing all the tasks
Again, these are just ideas for what must be completed to win. The marathon aspect of it allows you to essentially get the same benefit of multiple different contests all in one.
