As someone who uses the search function on HN regularly I have to agree its pretty jarring to see how many webpages totally disappear. Thankfully the wayback machine exists.

There was a thread on Google forums about that, and I recall many upset users asking for the option to be reactivated, but (the irony) that discussion was removed as well.

It's pretty slow, though.
Therefore I try to save webpages that I care about, but it's getting harder and harder. Not to mention the space it takes - is it really worth the hundreds of GiB of personal archives when I'll likely want - not need - maybe a few KiBs of it decades down the line. And even then, will I be able to find it?
Sometimes I think about just archiving a screenshot and the text of websites, instead of markup and related files.
