If you are interested in Web 2.0 and where it’s going, you are probably interested in invitations to new web services. The invites in which I am most interested are delicious 2.0 (preview) and fav.or.it (preview).
This shows me to be something of a laggard among the Web 2.0 trendhounds. The first of these is one of the founding services of Web 2.0, while the second is about comments on those archaic blog things. In defense of my trendiness, I am interested in web identity, and am trying very hard to be interested in social network aggregation.
