Everything matters. Saying logos matter is matters is somewhat meaningless. The question is how much do they matter? How much do they matter at one specific moment in time? How much time can you afford to spend on the logo problem at a moment in time?
I shared this story because I suspect there are a lot of people who would be willing to spend $30 to try getting a cheap logo for their startup/side project/whatever.
I really don't think you should feel threatened by it if you're able to communicate what value you're adding to a company by applying your unique design skills.
