Well, I suppose time will tell. I'm only speaking from experience at having built several multi-million dollar businesses from scratch and working at one of the Big 6 ad firms.
Whether the emotional connection is done with a catchy tune or good marketing or a mascot or whatever, it'll be quite integral to the long-term success of this coin.
I can only hope that we will populate our forums and meeting tables with the kinds of people that will ultimately use the product (not just technical people). Not doing so would be a big mistake.
I think the problem here is that you're trying to sell a product, and Vertcoin is a service. That kind of marketing can work for service brands ("For everything else there's Mastercard") but I really don't see how adding a cute mascot, at this stage, would help in any way. Jingles are for television adverts, "good marketing" is too vague to discuss. What exactly do you propose? Bear in mind you're trying to sell something that doesn't have intrinsic benefits for anyone other than the people mining it. I think Vertcoin's viability rests solely on adoption by miners, at least in these early days. You won't convince them to come with cute or sexy marketing; either they'll see the potential in the gains that the algo provides, or they won't. I'm taking a fairly long view here. Litecoin didn't start out valuable, it became valuable because the mining community adopted it in response to FPGAs/ASICs. The network conditions that kind of situation creates validate the currency, and I hope to see the same for Vertcoin.
That's my take, anyway. I welcome criticism.
