I nearly deleted my comment because I felt bad after the author replied and also because I generally want to encourage people to publish stuff they are not confident about -- and I would never have posted this about a personal blog.

But I decided to leave it because I think I stand by the implication that reputation for specific technical blogs can be earned or used up. Fly.io has earned a lot of reputation and I (and I guess others) clicked on a title I would not usually have because I saw the domain. In this case I feel like some reputation was "used up" and I am (slightly) less likely to click on a post solely because I see a fly.io domain in future.

Maybe I am just not the target audience for the post and it is better than my assessment, but if not then I think people value HN as an honest audience that doesn't hold back on criticism (I know I do and I have received harsh but valid criticism from hn on stuff I have written).

Fly.io can probably keep making front page based on reputation if there is a balance of very high quality content and other posts, but I feel like something like this could have been 1000% better with another revision round and some editing (probably only 20% more effort) so I will keep saying stuff like this I guess?
