I am actually working on a book for exactly this - I consult with start up founders all the time on their marketing and there is a TON of misinformation for them to deal with on top of the fear talked about here and a host of other issues. There are plenty of generic marketing books, but mine is focused specifically on startup founders. For example: almost every digital marketing book out there will say you need a blog for SEO reasons, the reality is you shouldn't bother with that until you are further along with your business most of the time (and I'll go into detail on the why in the book). A startup founder has super limited time and money, so talking about the optimal set up (tweet X number of times, Post X number of blog posts) may not be helpful when there are things that take up way less time that may be far more valuable. Eg. knowing exactly where your perfect customer hangs out can be more valuable, especially so your tweets or blog posts don't just disappear into the nether.
