I was recently trying to find the best price for internet service in my area and came across a question asking me how much RAM my computer has. I was surprised by the options in the dropdown.

Luckily I had at least the minimum requirements.
I forgot to post a link to this earlier, but I wrote a blog post on using jQuery and YQL to get an RSS feed from a web site. The code uses YQL to grab the content of the external site and then jQuery to find a link tag pointing to the location of the RSS feed. This is similar to how Firefox displays the RSS feed icon in the address bar.
