Actually I did the wikis exercise before Flickr, on this very same day... I just forgot to blog. As usual, I chose an easy option - to edit the library entry. And as usual, I clicked too fast and didn't pay enough attention to details on the screen before calling for help. I got Brian on the phone and asked him why I was not seeing the text to edit when I clicked on "edit". Almost immediately after I hung up, I got the text screen. Fortunately, I did find something less dumb for Brian to help me out - comparing my edits with previous ones. However, I still don't know how I can track the complete history of edits, as I could only compare two versions at one time.
I think I like the collaborative way of writing and see potentials for lots of work situations that can employ this. The first things coming to mind are the AV or Reserve web pages or the copyright FAQ. I can never forget the number of hours spent on e-mailing with one another versions 8,9 and 10 of the same script. I'd love to use wikis for my next update on these pages!
