Another reason not to procrastinate on the name, logo, etc: Almost everyone starts more than one product/company. Most of these fail. I seem to remember that 30% of YC companies change their product during YC.
I can tell you from experience - the 5th time that I had to come up with a name/logo for a company, because I switched to a new idea, I already understood that this was not a productive use of time.
