Hmmm, reminds me of an old saying, "When in doubt, leave it out." Now I'm going back to all my forms and mockups, wondering if there's anything else that can be removed. Short attention spans, human nature, and plain old laziness make "Keep It Simple Stupid" more relevant than ever.
A domain name doesn't win you a market; launching second or fifth or tenth doesn't lose you a market. You can't blame your competitors or your board or the lack of or excess of investment. Focus on what really matters: making users happy with your product as quickly as you can, and helping them as much as you can after that. If you do those better than anyone else out there you'll win.
