I find the name OppenUp.com utterly puzzling. And I'd predict that the name will be forgotten (or misremembered) immediately after hearing it or seeing it, thereby nullifying most of your marketing efforts and requiring additional advertising expenditures to compensate ... unless, of course, your audience is composed mainly of the fans of objectivist poet, George Oppen!

Sorry if that's a bit bleak. Honestly, this is a clear example of when a name change is necessary.

Your name (and your domain name) are part of your brand. It's not simply a place holder for online content. A bad choice will cost you money. The opposite is also true. A good name / domain will render all your branding and marketing more efficient, which translates into a larger audience at less cost ... on an ongoing basis.

Since names / domains have financial implications, I recommend talking to a professional who does this stuff full time. I'm one (surprise surprise). But there are a few others on Clarity.fm as well.
