I did not come on HN 3 years ago, so yes, relevant for a number of users (and the majority, probably) since HN has grown significantly over the past few years.
NOpe, I do not remember seeing this 3 years ago. I must have missed it somehow. I do not really understand the issue with having a story in top 30 that does not interest you, however. Do you have to click on all of them to feel happy and content, or having one you have already seen before ruins your day ? :)
Besides, the same news viewed 3 years, 5 years, 10 years down the road is not the same news per se, because it gains a different perspective over time. I believe it is valuable.
It's pretty easy for a story to be on the front page for a while, get thoroughly discussed, then drop off before you see it, especially if you're, you know, hacking.
