After much deliberation, I voted for masscoin.

My reasons are as follows.

Easy to spell and say. It rolls off the tongue well.
Serious. The moola and ching are too cartoon-ish to invoke serious investors.
Positive name because mass implies strength in size and numbers. Most of the other names convey negativity or at least lack of positivity.
No undesirable meaning, except if one assumes it is a heavy coin. Worse for example silicoin might have something to with silicone rubber and even breast implants, and bionicoin implies a mechanical and physical apparatus.
Unlike Bitcoin, a coin which can only be mined from PCs would be a coin of the masses.
Unlike Bitcoin, a coin which was resistant to centralization would be a coin of the masses.
Unlike Bitcoin, a coin in which nearly every user is anonymous would be a coin of the masses.
Best altcoins will stand out regardless if their name contains coin and names without coin, cash, bucks or money do not instantly convey correct meaning to most people. It will be very difficult to brand a name without one of those words and especially given Bitcoin's marketing lead and network effects.
Good it doesn't contain gold which is paradoxical to the internet.
My definition of matter is that mass is an emergent Shannon information (entropy) effect, i.e. inertial frames exist for information that stimulate real effects analogous to tangible effects that stimulate physical senses and outcomes. The distinction is arbitrary.

I saw that masscoin.com was for sale for $57, so I purchased it. What a steal. I paid $500 for coolpage.com in the late 1990s when the internet was orders-of-magnitude smaller. I will transfer this to you if you decide to choose masscoin. Perhaps you can send me some masscoins in the future to pay me back.
