"Getting all of your books off of Amazon" is a long way from "host servers in your house to store all of your media". I've worked hard over the last few months to get my books all into open epub format for my own use, and it's been fantastic, but my 267 books only take up 2.3GB. It's nothing. I keep a local copy and also tossed them into Dropbox as another backup. You can own your stuff without necessarily having to build these big robust systems.

It's where Brian McClendon (he co-founded Keyhole, which became Google Earth) grew up. In fact, if you load up Google Earth on your home computer and simply zoom in ([Page Up] or [+]), you'll land in the Lawrence-based apartment complex where he was raised.

I agree. Tablets are big enough to handle a standard SD card -- why force them to use microSD?

It seems to me that Q&A is the answer, if done properly. The key is to ask something that can only be answered if you're on the site. For example: "Next to the Slashdot logo at the top-left of the page, there is a five-word phrase. What is the second word in that phrase?"

You'd obviously need to change it up fairly often (and large sites would have problems still), but spammers would have a difficult time keeping track of answers for thousands of sites.

To make it even better, have it rotate through a few similar questions for your site, and have the questions be buried CAPTCHA-style in an image.

All told, it would seem to help. They'd have to resolve a very long CAPTCHA (117 characters in my example above) AND be on the site to get the answer. Seems like it would help.
