Sad point of the day: Seeing a bunch of interesting concept papers (lilo's diary entries) disappear off Advogato. I hope they come back. I'm not sure I agree with everything that was in them, but they have been tought-provoking and interesting. (Those that have been flaming him away: Shame on you!)
Personally dangerous point of the day (or rather, last night): Got partially hooked on Everything 2. Starting to write up nodes there is a recursive loop - you always find something you want to link to, and thus have to create ever more nodes.
The Everything experience, combined with previous inspections of WikiWikiWeb, has led me to conlude that Ted Nelson (the original inventor of hypertext and initator the Xanadu project, started 1960) was right: You do need some way of hooking together multiple nodes of text (he calls them 'berts' or somesuch) to form a coherent text stream, but still be able to connect different sets of them for form different streams. Neither linear text nor traditional node/page based hypertext is enough, and thus all of the web, Everything, and WikiWikiWeb fail to live up to the original promise of hypertext. Everything and Wiki comes closer than the overall web, though.
