Note that testnet operates under the threat of being reset at any
time, if someone comes along and destroys its usefulness with spam or
mining or whatnot.  That guarantees it remains a testing tool, and not
a real alt-currency.  The current testnet is the third iteration,
hence you see "testnet3" in some source code.

This option is always available for any merge-mined chain as well,
ensuring little real value is assigned to the test chain.

But that is a binary decision:  If you don't have a reset-the-chain
policy, you have a de facto "it is a real currency" policy.

A fork of the bitcoin.git codebase has the nice attribute of making it
easy to "upstream" any useful changes that are not specific to that
one alt-coin.

What's neat about bitcoin is that it invented a whole new /category/
of technology.  It's not just /an/ invention, but opened up all this
new experimentation with the new concept of money itself.

However for the bitcoin.git reference implementation, it makes more
sense to focus on supporting existing bitcoin users.  That permits
alt-coins to bubble up (or not) organically, and at the same time
reduces user confusion.  We have enough trouble explaining the basics
of bitcoin to the world; trying to keep follow every alt-coin
bandwagon just muddies the waters from a messaging standpoint.

alt-coin changes fall into two categories:
1) Rule changes.  We don't want these.
2) Generic bug fixes, cleanups, changes etc.  It would be nice to see
improvements bubble up, benefitting everybody.
