Define enthusiast.

Is someone an enthusiast if they have a blockchain.info wallet, but have never owned more than a few fractions of a bitcoin from one of the faucets?

How about if they occasionally use bitcoin for purchases in a niche market, but nothing else?

If they have the reference client installed, but only run it when they want to make a tranasction?

If they use it, but have no understanding at all about how/why it works, and what it's benefits are?

What about someone who has a decent understanding about how it all works, but isn't interested in using it?

Perhaps someone who understands it well, and uses it for transactions, but doesn't contribute beyond that?

Someone who mines, and immediately sells for their local currency, but has no idea whay they are mining, or why it makes them money?

Does a person have to actually contribute programming skills to the project to be considered an "enthusiast"?
