Barriers to Technology

What are the barriers to technology?  It is an easy answer for me.  Training.  As teachers, we are giving a lot of ideas for technology use, but very little PD.  We are also show new ideas but we do not have a network of help.  A lot of our administrators have been out of the classroom since technology has really taken off.  They can't help and are not able to give use real world examples.  We can all find videos on any type of technological ideas in education, yet we have no support team handily available.  Until there is support, and support from the top, we will never use technology to its greatest potential.
