Let me prefix this post with this: I am Australian, and the other company is American.
I've been working on an idea on the side for the last month or so, and just saw that another company obviously had the same cool idea and implemented it in a very similar way to what I had planned (in the states). There is nothing like it offered in Australia, though.
Should I continue with it and throw it out there knowing that if the American version really takes off, I will possibly be labelled as "X for Australians"? Or should I find a (possibly less good) way of implementing this _just to be different_?
Anyone done this before?
Don't be intimidated by competition and aim for the global market when you launch. If you work hard and listen to your customers it is entirely possible that you'll win in the marketplace. Both you and them are going to run into the same problem: finding customers. And it isn't like their existence makes that much more difficult for you. Maybe even easier since a trend is sometimes a story and articles about them might even mention you.
