My personal opinion is that Vector is an establised name and changing it would confuse people. Once established, changing a name is kind of suicide to the distro.
For instance, when I was a really green newbie, I was fascinated by Vector, but just didn't have the knowledge and gumption to install it. I thought it was harder to do that it really was/is. So, I used other, easier to install distros for a while, those that did the partitioning for you, but continued to come back to Vector. I would google Vector and come to your site. If you had changed the name, I wouldn't have re-found you.
The only thing Vector might need is a lot more exposure to the public; more advertising, etc.
I now have installed Vector and am using it right now. It's great! A newbie can use it easily, and a Slackware guru can use it to. Perfect. JMHO.
