i hear this often. and i've worked with some people like that, many of whom i admire (in some ways).
yet i am not at all opinionated (as far as i can tell). when people ask me for advice, i often find it very hard to guide them because there are so many options, and what will work best seems to depend so much on non-technical factors.
and i am not sure what to do about this. i have tried being more opinionated, and there are times when a decision affected my work and i have fought for what was right, because i am doing the work. but often other people, opinionating, just seem like noise (worse, sometimes i suspect people confuse being opinionated with understanding something).
no real conclusion here, sorry. sometimes i wonder if people are too opinionated; sometimes i wonder if i am not opinionated enough (or if i am not that talented - although i do take re-assurance from the d-k effect). but that part of the post, and a related comment by the author here, disturbed me a little. i am not sure a place full of opinionated people is that pleasant (or optimal).
i was wondering if this touches a chord with anyone else?
