Hey, LJToys sounds kinda neat.  What's it do?

LJToys is a bunch of utilities for tracking hits things to do with your livejournal.  Its fairly clever, some might even say sneaky, but all jolly good fun.  Through using LJToys you may learn of the following things:

• Who's read your posts
• Physical location they were read from (ip address, country, can be mapped to an individual lj user)
• Changes to people's friend lists - mailed to you every night
• Details of anyone who's added you to their friends list - easier than checking your userinfo page every day :P
• Who really reads your journal. And who doesn't. [Paid feature]
• Cute li'l charts of who's been reading your journal most
• The ever-popular ljtoys meme!
• Info on individual LJ users - how often we've spotted them & where from (and that last bit can be pretty interesting...)

Also there's a bunch of extra-cool new stuff:

• Custom web bugs - drop these into a web page and hits to it will magically appear in your readers list [paid accounts]
• Graphs!  Beautiful graphs of how many hits your journal has had each day.
• Anonymous comment identification - LJToys tries to guess who made an anon. comment based on which of your friends were using LiveJournal at the time.  An inexact science but hey, it kinda works.  [Paid accounts]
