Google never ceases to amaze me. I browsed over to Google Labs today (
http://labs.google.com ) and noticed this tool named Google Sets (
http://labs.google.com/sets ). Enter 2 or 3 items and Google Sets will create a set for you. For instance, type in dwarves, humans and elves and it will give you a list of RPG and mythical races. Type in song names and you'll get more song names by the same group. For instance, I typed in only two titles, "Black" and "Alive", and it gave me a whole list of Pearl Jam songs! I think it's pretty amazing, and could prove to be a useful tool.
