There are all kinds of places were things are cached, both on- and offline. Your data may end up in:

* Browser caches.

* Sites like wayback machine or search engines that make copies of webpages and save them.

* Tools that store data downloaded from the web, e.g. RSS readers.

* Caching proxies.

* the list goes on and on.

I think what tptacek wanted to say: It's just so common that people download things from the web and store them without even thinking much about it. And all those places where this happens now potentially can contain sensitive data.
