Reputation, membership, sense of community -- none of that could be automatically replicated by replicating the "site" and all of those things play a big role in making it what it is, giving it the value it has, causing it to function the way it does.

I believe in reincarnation, so I believe our minds are separate from our bodies and go on after our bodies cease to function. I mean, what is "life" anyway? What causes a physical construct to be a living, breathing entity one second and dead the next?

Life. Magic. Pretty much the same, I think.
