And I also upvoted your comment because I thought it was valuable and noteworthy. :) I really wasn't meaning to be critical to you in my response here.

HN seems kind of hesitant to add additional profile tools beyond the usual. I'm not sure if that's part of it's charm or a detriment. I think having a sig line on every comment might be tedious, and FWIW, I don't think it should be obligatory to attach your employer to every comment on every post on HN. There's a lot that's simply not remotely relevant.
