You'd have to look back at the ones I quoted. Obviously, some of the suggestions were less serious than others.
If you don't feel like going back, just list your suggestions; if any are duplicates they'll just be tossed out before the poll choices are chosen.
Obviously ? Really ? Who's opinion ?
How do you judge less or more serious ?
All the judgements should be made by voting, not by one individual.
OK, you set the 0.1 BTC prize and you can send it to anyone you like, but if this is not a fair game or some of us don't think it's a fair game, then it may end up less people would use the name you decided for 0.0001 btc.
So, to make less complains as possible, to make more people willing to use the name in the future, I strongly suggest that :
Don't be obvious. Put all the names in the poll, if it is obvious then let the voting say so.
too much "in your face" for the good of Bitcoin in general. It may be that the Hayek would be more appropriate from a marketing perspective.
