Thanks for pointing out the unescape, something I hadn't thought of. 
Unfortunately, as I'm using it at least, that didn't fix the problem. It 
works when I do this:

@linky = "http%3A%2F%2Fpracticalpedal.com"
@linky = CGI.unescape(@linky)
@result = open(@linky)
@doc = Hpricot(@result)
@title = (@doc/"title").inner_html
@result.close
puts @title

But it gives me a 500 Internal Server Error when I do this:

cgi = CGI.new
@linky = cgi['link']
@linky = CGI.unescape(@linky)
@result = open(@linky)
@doc = Hpricot(@result)
@title = (@doc/"title").inner_html
@result.close
puts @title

I'm pretty sure the @linky = cgi['link'] is working because when I 
remove the hpricot part of the code and just display the variable with a 
puts @linky, I get the correct string as output.
