These are my favourate web2 tools for mathematics:
The Moodle VLE + integrated forum
Joomla content management system to collaborate
and of course GeoGebra dynamic software for mathematics

This is a good thread!
What I like more, to work with students:
- blogs
- Modellus (a powerful mathematical and science modelling tool)
- dropbox, to exchange files with them in a shared cloud space
