Yup, expect a downvote for this comment too. And it is ok. Comments should add something. A "plus one" is insufficient and can just be an upvote. Conversely, a plus one with an anecdote or link to data or similar content is usually well received.

As for the comment that got downvotes above, the general view is that low hanging humor will degrade the site experience and I agree. Slashdot was a popular tech site but you could always expect upvotes for "first post," or "i for one welcome our new humor-avoiding overlords." A lot of quality slipped over time.

Cheers and welcome to HN
