If you do NOT have your site localized, did you specifically choose not to? Why?

If your site IS localized:
- Did you get it all professionally translated or machine translated?
- How do you keep it updated as you modify/add sections/etc?
- Is display not an issue? For example, if I have 3 columns of words in a 200px wide columns and the total letter count is 20 in English for 44 in French, it would span too wide... and not look as expected? Has this sort of a thing proven to be an issue? How did/do you tackle it?
