I don't think this is fair. The mods want the site to be successful and the parent is pointing out something that should be a cause for concern for them. No one wants HN to turn into the next Slashdot.
But a bug report that says "Your program seems to have gotten slower over the past four years and I feel like it's crashing more often. Please fix it" isn't very useful. A couple of concrete examples of specific problems with some suggestions on what should have been done in those cases would have made the post much more informative.
