It kind of irritates me how some things are not available in some countries, while they should be.
Good example here, text message Twitter. It’s available in a lot of countries now, but not in the Netherlands. Why?
Okay, providers and whatnot may put limit on the things that can be done, but what do they gain from it? As far as I can know, nothing. They’re just keeping a lot of people from doing what they want.
Especially with paid services, it’s smart to cross country borders. This broadens your customer range, and thus earns you more.
It may take a while to make sure everything works properly, for example with credit card things, but it’ll be more than worth it.
