Teaching & Technology Issue

I was thinking, what kind of issue would I want to research for a Teaching & Technology Issues blog. Then I though, there's all kinds of information out there on the internet, so how can you tell what is legit information and what is phony garbage or incomplete biased information? And, how can you teach students how to wade through the bad to get down to the good stuff? I'll be looking into that over the next few weeks and post my findings here, so keep a look out to see if anything might be worth using or teaching in your classroom.
