If you want to have a really good 23 slide summary of where the web is heading, check out Nova Spivack’s Web Evolution slide deck.

There are some really good positioning slides as from slide #9 and following, to get a feel for the difference between for ex Delicious, Google, Powerset (now Microsoft), Twine, and Wolfram Alpha.
I was quite lucky having a 1-1 with Nova Spivack during Web 2.0 Summit in October 2009. He showed me a much elaborated slide deck than this one, but I feel that since then he really condensed the subject to the essential.
Enjoy !
PS: He was ok to join Innotribe @ Sibos 2010 in Amsterdam 😉
