Glad you like it.. perhaps I'd add one more:

- Images are the primary means we use to get code, and sometimes 
content, into the hands of users. They are like a snapshot of a running 
system - as if someone installed a linux distribution plus packages of 
interest, configured everything, started a bunch of applications 
running, did a suspend-to-disk and shipped you the disk so you could 
resume where they left off. A number of images are maintained and 
released periodically, including the official squeak images (3.7, 3.8, 
3.9...), the squeakland images (05, 06...) and project-specific images 
(croquet, tweak, seaside, smallwiki, spoon...).
