Rather than an approach like this, which can
only serve to produce an echo-chamber effect, can I recommend the Hacker News Enhancement Suite for Chrome (
https://chrome.google.com/webstore/detail/hacker-news-enhanc...)? It remembers the upvotes and downvotes you cast per-user, which provides a very quick at-a-glance reminder of your past opinions of a given member's contributions, and allows you to make a more informed decision about whether or not to engage with them.
This is coming from someone with showdead on, FWIW. I rather like seeing the things that others have deemed "not worth seeing".
