Pretty limited. The cellular connection only connects to amazon.com and Wikipedia

The Kindle also comes with an "Experimental Browser". [1] I've used it on an old Kindle to read the news, craigslist. I'm not sure if it supports JS.

I once drove 10 hours to visit a friend but my phone was dead on arrival. I had his address but no apartment number. I used the Kindle experimental browser to message him on facebook.

The big problem with the Experimental Browser on my beloved Kindle DX is that it doesn't seem to support tls/https.

Otherwise I'd use it a lot more.

It's been probably a couple of years, but I tried to load HN in it once and it was unreadable, so I don't think it's too great.

I read HN on my Kindle's browser fairly regularly. HN itself (and similar pages with a simple layout, such as i.reddit.com) works great. For the articles that are linked, it's a coin flip whether it works or the page has so much cruft that it crashes the browser.

I used to use the built-in browser to load Google Voice and Google Talk and they worked fine. Of course, this was before they were overhauled into bloated, JS-heavy pages that barely run on non-Chrome mobile browsers.

You can write a proxy that creates a new page on Wikipedia with the requested URL. A remote machine then monitors the page, downloads the URL, and adds to a new Wikipedia page.

I think the Wikipedia editors would ban the proxy's IP pretty quickly for making junk pages.

I imagine they track usage and block accounts that abuse the service.
