Plan B for Web 2.0 Presentation

I have close to ten Web 2.0 tools to present in 50 minutes. This should be alright if the Internet is fast at school. But it wasn't when I checked yesterday. So here I am, adding more slides with screenshots just in case I won't be able to download fast enough.

Well, this is Plan C. Plan B is to download all the sites before the presentation, and minimize the screen.

The tools I will be presenting, with examples by teachers and students are:
Voicethread
Wikispaces and Wetpaint
Panraven, Comiqs, Tikatok
(Ma.gnolia), Diigo, Clipmarks
TeacherTube (SchoolTube, LearnOutLoud)
LibraryThing
GoogleReader and iGoogle
