That aside, I think a lot of this is relative to where one is at in terms of education, network, support structure, access to capital, and a raft of other factors
Eg, if you're an MBA with a deep and narrow understanding of a certain niche, you're not going to lean on startup blogs in the same way an enterprising trucker from Wyoming is who's fuelling the hustle with Youtube tutorials on Java and epub torrents.
Entrepreneurship is a very long and lonely road, so it's perfectly reasonable that many of us look at these sites to (re)validate our decision to take a risk and steer off-course in our career choices from the rest of our peers.
I suffer from this in many ways, not just shipping a product, but even when just starting a dumb side project it is easy to get sidetracked with simple decisions, such as language, framework, etc.(the infamous JS fatigue)
So forget about perfect and just do it. Once you start moving it is easier to get going. You will get a chance to improve things later on.
