Vietnamese girl travels to 25 countries with US $700

This article is a little short on details on how she accomplished this, which is what I'd be most interested in. Couchsurfing means that she saved a ton of money, but it's only one of three major expenses (besides food and transportation).

-- Did she work legally in those other countries? -- What were her main modes of transportation between countries?

And because I'm a cynic...

-- How many of her new "friends" were simply men looking to take advantage of her?

This is almost fascinating, but the article is short on details.

I really want to know how she got across borders; did she need visas? How did she choose which country to go to?
