Web 2.0 a personal learning journey

Having signed up for various web based tools, wikispaces, google groups, blogging tools, social bookmarking and you get the idea, I am now in serious risk of suffering password and username meltdown.

How can we expect learners / students to cope especially if we want to introduce them to new tools. The obvious solution seems to be to use what learners already use and tie it all together with RSS feeds but darned if I can figure out how this would ork in practice with a group of students.
