I think that the most applicable information is not a software package or the use of technology in my classroom.
I think it is rather an attitude. 

We all have shared stories of colleagues who refuse to learn new techniques. Fortunately, we have more in the camp of sharing.

We all have fellow teachers who refuse to admit that students - all our students - are changing (the core of our students is still there - a willingness to work and learn).  Again, most of us are evolving.

I am fortunate to be in a position of teaching in a computer lab with an administration that provides constant hardware/software updates - that values what I do with my students.

If I had to single out one piece - it would be VoiceThread.
