Okiedoke. I wasn't doing anything except throwing an interesting tidbit out there. Personally, I find the whale/dolphin distinction (or lack thereof) fairly interesting. So I shared it. Your comment added more interesting information to the mix. I believe this sharing of information that is related to the post is what comments are for, and I think it's a worthy use of them. It's especially what threaded comments are for. See, I can't derail a whole conversation-- I can just lead a small subthread away from the main flow. So, I figured this was an OK comment to post on Hacker News.
