I don't understand all this hate. Unlike US-only offerings, Whimsical is a service that's trying to open up to readers of Hacker News from other countries.
As some have already pointed out, it is not easy to go International.
On top of that, I'm sure by now you've realized that HackerNews has many international readers and they'd be very happy to see services that were previously only in the US with no plans of going international have some International competition.
I'm sorry that some of you are not entertained, but for the rest of us, HackerNews is a great place to Show and talk about what we're working on and get advice on how we could do it better!
