You can enter bugs bunny or whatever you want in the name field, just FYI, although your second point above is entirely correct.

I think another thing that boosts Poloniex position in volume is that many people use shapeshift now, and shapeshift buys their coins at the exchange with the best liquidity, so it's kind of a liquidity begets liquidity catch-22 at this point. Just the other day I read on reddit about some retard that was storing coins on poloniex using them as a wallet, and trying to convert them to different coins using shapeshift; like, wtf dude?

Anyway, I think bitfinex will probably start to pick up some more volume, and maybe then we'll see it added to btc-e or something which would further help.
