Most useful web 2.0 tools

The web 2.0 world seems pretty daunting at times, with so many different accronyms, and cute little names that I haven't heard of. So I was interested to come across a presentation which focused on a handful of web 2.0 tools - the ones deemed the most important for school administrators:

Il2007 Librarian 2.0:
Supporting Administrators with Web 2.0 Tools

The presentation is by Carolyn Foote, a librarian at a large public suburban high school, Westlake High School, in Austin, Texas. She blogs at
Not So Distant Future
technology, libraries, and schools

Here are some ideas for the most essential web 2.0 tools, sent to Carolyn via Twitter:

• Google Docs, RSS, Blogger, Twitter
• Blogs, RSS, wikis, twitter, Google Docs
• wikis, igoogle, google calendar, zoho docs
• moodle, google docs, wikis

Carolyn's presentation focused on:

• Blogs, mentioning edublogs
• podcasts, discussing tools for these
• wikis, mentioning pbwikis and wikispaces, and showing an example of creating a calandar on a wiki (from a connectedlibraries wiki)
• other tools - including google alerts, google docs, google calendar, del.icio.us (technolibrary bookmarks), jott, bloglines, pageflakes, bloglines (rss agregrator),
  
• finishing with the connected libraries wiki, which contains a collection of instructions for using different web 2.0 tools in schools

I have bolded the ones I have absolutely no idea about!
