I hope this is true! I've been developing for 12+ years, and always had an interest in marketing, but never really studied marketing. Now, I'm one of three tech co-founders of a startup that does not yet have a dedicated marketing person. So, I've finally been diving into really trying to learn and understand marketing (and sales).
OK, wait, I did take "Marketing 101" at the local community college a couple of years ago, but that's the only formal education on the topic I've had.
Now, I have a huge stack of sales and marketing books I'm working through. So far I've mainly focused on the Jack Trout, Al Ries, et al. stuff... Positioning, Re-positioning, The 22 Immutable Laws of Marketing, etc., and I've been going through a video series from Chet Holmes (of The Ultimate Sales Machine fame).
Looks like some good resources in the linked article, so looking forward to chewing through some of that as well. And here's a pre-emptive "+1" for more good startup marketing related links on HN!
