First: I use neomutt + mbsync (formerly isync) + notmuch. The local searching was at first a nerd special interest project but has actually become very useful for searching, filtering and otherwise managing my mail.

Second: the button on the article to submit to HN seems to be somewhat... off? I wouldn't mind one that would submit in the first instance and then link to the HN thread on subsequent clicks but having a button that just loads a round into the chamber for all users clicking on it seems like incitement to blogspam.
