It's the first time I've ever commented that, and I was trying to figure out a way to omit it. I don't like that sort of phrase either, I especially hate comments that just go "This.", but they're rare on HN so I'm in good company.

Ultimately, I put it because:

- It was the most directly informative comment on the thread;

- It had been downvoted (greyed out) to the very bottom of the thread; and

- I wanted to express my support before making a fairly orthogonal comment without whiplashing everyone.

The whiplashing concern is the problem I run into most generally. It can be hard to reply to someone with a somewhat related idea without making it seem like you're contradicting them, particularly if they're being dogpiled on with downvotes or comments. I'd love to hear other ways to go about this, I'm always trying to improve my communication.
