Every so often my application Glutt would gather information from Glitch. I would crawl action data, Item Information, recent SDBs and recent Sales.
I also tweeted the 'best deal' every several hours (and keep record of each tweet) on @feedyourglutt. Results might be kind of interesting.
In total, I've gathered over 150MB of information. Due to it's size, I have not dumped it anywhere yet. However, if any one is interested in this data let me know and we can arrange the best way to transfer it.
I will check this forum, you can also contact me here: nathangraves.com/contact.php
