Nope, it does not work for me anymore. So I was inspired by it and made another that does mostly the same. It also removes nonmatching posts and highlights matching terms.

https://github.com/joelgardner/hnfilter

hn_filter(['rem-ote'], ['re-act', 'javas-cript'], true) will remove posts that don't contain 'rem-ote' and one of 're-act'|'javas-cript' (remove the dashes obviously)

It's because the CSS class changed from "athing" to "storylink".
