I don't believe it's spam since there are new two features, OpenZones and hurricane tracks, that are interesting and useful to people, especially with the hurricane. I'm quite proud of these developments. The OpenZones meet public good while still having a way to cover costs. The hurricane tracks visualization is new and unique and addresses the problem highlighted in the "Misinterpreting hurricane forecasts"[0]. I believe these are appropriate for "Show HN".
I have many other ideas to develop for Flowx, it would be sad if they could not be shown here because it's in a product.
BTW, the guidelines say this about spam: "Please don't complain that a submission is inappropriate. If a story is spam or off-topic, flag it. Don't feed egregious comments by replying; flag them instead. If you flag, please don't also comment that you did."
