Touchmines was only released yesterday at 3pm, but the response has been amazing! I've already had over 4000 downloads on the first day alone! One thing that struck me was the lack of downloads from the foreign markets relative to the english speaking countries like the US, Canada, and Great Britain.
If you're an iPhone developer, you really need to keep in mind the global audience you're releasing to. My next major step is to localize the product descriptions into as many languages as possible, as well as either localize the app or eliminate the text entirely. I'd rather just use icons for the whole interface, as it reduces the amount of work required for localization and is hopefully more elegant for everyone.
Now I just need to find people willing to translate a few paragraphs into their native language for a beer or two, and maybe ask some experienced developers about their own localization processes. I'm most afraid of using symbols or colours that would be seen as distasteful or unlucky in a foreign culture, since I'm a fairly sheltered north american!
