Twas not me who downvoted you. I did not even know before today that HN won't let me downvote any comment on my own submission (unless you need more points for that too). Only the upvote arrows appear for me here.
You may not be grumpy, but having many short questions with a sarcastic tone ("cute") or negative slant comes across very aggressively. I realize the website may not provide all the answers to someone who has no knowledge of the domain (sailing), but I think it provided enough visuals and information for someone approaching it with an inquisitive mind.
As a techie and HN user, I'm interested in technology and websites, and one thing I want is for websites to appropriately convey their messages. This one simply doesn't convey necessary information to people who don't know what they're looking at. Is that a problem? Not necessarily. It depends on the audience.
Also note that at the end I offered a solution to the problems I mentioned. If I were grumpy and a jerk, I would have simply complained. It just so happens that I'm trying to help.
Thanks for the downvotes though! Carry on.
