There are second order effects. You definitely attract different types of talent depending on the technology stack of choice. And building the right group of talent around an early stage product/company is an extremely impactful thing on the product. And blogs are an impactful talent marketing source.
This doesn't guarantee any sort of commercial success because there are so many follow on things that are important (product/market fit, sales, customer success, etc.) but it's pretty rough to succeed in the follow ons when the product itself is shit.
For first order effects, if a product's target market is developer oriented, then marketing to things developers care about such as a programming language will help initial adoption. It can also help the tool get talked about more organically via user blogs, social media, word of mouth, etc.
Basically, yeah, it matters, but as a cog in a big machine like all things.
