Great ideas that will probably be blocked

I am excited about the possibility of increasing the level of student engagement throught the use of instructional technology. However, I am very worried about student blogs and wikis being blocked by our firewall. Everything is very locked down on our district network. This is true for teachers and students alike. I think the use of blogs and wikis can capture student's attention and get them excited about managing their own learning. It will be a real shame if all of this creativity ends up not being possible due to network security protocols.
