Actually you're wrong. You don't have to root. I've been sideloading on my Backflip and Galaxy S without rooting for a long time now. Easiest way is to just use Droid Explorer. This is how I show non-tech savvy users to sideload. It's a free app that makes installing APKs completely painless. You can also install the android SDK (a free download) and type in "adb install "

Even on the most locked down Android phones, you can still side-load applications without jailbreaking or rooting the phone.

Because HTML rendering automatically removes extra white space beyond the first spce. If you type in two spaces, as I have here, it will automatically truncate when rendering down to one space. If you want HTML rendering the spaces properly you have to tell it to.

If your only idea of "security" is to not link to a page, you've got other problems. If you don't want google caching it, use a htaccess to block access, or use the robots file to tell google not to index it. You're the only one to blame here, not Google.
