ASP.NET: when to start worrying about globalisation, localisation? Before, while or at the end?

I've followed a interesting tutorial on how to use Resource.resxfile files to allow the webside to be viewed by users from different cultures.

Now, I'd like to know when to start worrying about globalisation, localisation? Before, while or at开发者_C百科 the end?

Is globalization a requirement of your application? If so, then worry about it immediately.

If it's not a requirement, then don't worry about it at all.

John is absolutely right, if it's not a requirement, don't ever worry about it.

On the flip side, however, I don't think you need to worry about it immediately. For the most part moving strings to resources files covers about 80% of the localization work you'll have to do... and that's pretty easy to do.
