It's no longer possible to indicate assent by upvoting an existing comment - an undesirable side-effect of hiding karma on comments. As a result, I have to comment:

    Would anyone be interested in a post detailing traffic
    as a result of being written about in LifeHacker VS the
    HN front-page

Hell Yeah!

[tastefulwords]

Actually, it would still be possible to do that, if we instituted some sort of a HN-wide policy that the person who wants to gauge interest should make that to-be-upvoted comment -- that's because comment authors do see the pints of their own comments.
