Stan put forward:
Bitshares. You can bank on it.
This is extensible:
Bitshares. You can bet on it.
Bitshares. You can vote on it.
Bitshares. You can trade on it.
That's freaking awesome.
. That's genius at work.
Include all in one?
Bitshares.
Bank on it.
Bet on it.
Vote on it.
Trade on it.
AWESOME...
Code on it. (turing scripting)
Work on it. (delegates)
Buy on it. (openbazaar thingy)
Speculate on it. (obviously)
Hedge on it.
Spare (money) on it. (Fees, but also as a savings account)
I think this idea would be very successful if the long-term marketing plan is to appeal individually to different demographics with separate products and unique marketing campaigns. For example, in the context of presenting a new developer's package at the Bitshares developer's conference, the slogan seen everywhere would be "Bitshares. You can code on it." When targeting day-traders in online advertising, the campaign would read: "Bitshares. You can trade on it."
This would give over-arching unity and brand-uniqueness to separate marketing campaigns and use-case scenarios, and remain simplistic to the end-user who does not have to contemplate everything that Bitshares is and can be. In gaining user adoption, this type of simplicity is going to be important.
If it becomes a list in an all-in-one marketing slogan like:
Bitshares.
Code on it.
Shop on it.
Save on it.
Trade on it.
...
I think confusion will arise as to what Bitshares is. The message will be less powerful and adoption will be less as a result.
