Bookmarking in Diigo

I bookmarked the Drum Corps Planet site (tag: news, expert columns, opinions) and the Cornell University Ornithology Lab site(facts, theories about birds) to reflect two long time hobbies: marching music and bird watching.
I already make extensive use of the bookmarking function in Safari, but will likely continue to use Diigo because of the extra info that can be added and the ease of accessibility from any computer.

I had to fumble my way through the bookmarking process somewhat using Safari because the drop boxes and instructions vary from the summer course outline.  But, here I am at the end of week 3!
