By monkeying with Perl and the Google Web APIs, I've come up with a script that generates a weekly LiveJournal Top 40. As you know, Google tries to rank Web pages by popularity. My script just requests a Google search for all pages hosted by LiveJournal.com, then reports on them by username in the order they are returned.
Since this is the first week, everyone on the list is "new," of course. As time goes on, though, it should show how many consecutive weeks each journal has been on the list and how much they've changed in position from the previous week. (I may drop it down to being a monthly list if it doesn't look like it changes much from week to week.)
I know the page design is boring. (Page design? What page design?) :-) If you would like to offer suggestions or even do some complete makeovers, please feel free to send them to me.
