I was thinking it would be fun to release GoodCoin and EvilCoin just to see which one becomes more valuable.
Or: JesusCoin, AllahCoin, BuddhaCoin, VishnuCoin, AtheistCoin, etc. Who will have the most followers?!?
Or get national with: USACoin, ChinaCoin, JapanCoin, EUCoin, etc.
The coin author would set a date to evaluate the final results and declare a winner. That would also reinforce that these coins are not meant to have any long-term value so noobs are not tempted to buy and hoard them.
I like this idea! Temporary altcoins created for "races" to see who can mine the most would be fun to watch

Can we preorder BFLCoins?
Only if you promise to make them now... and promise to actually deliver them in August!
Then, just as you're about to launch, push the target date back 3 months for mysterious reasons.
That is actually a genius idea. Could have "ObamaCoin" vs "RomneyCoin" for election cycles.
