Blogging for Edcucational Leaders

I am new to blogging, unless you count Facebook as a blog.  I actually worry that using a blog may become just one more thing teachers need to check for information and may become a frustration if used as a communication venue.  But, to use it as a way of sharing with other leaders to work toward solving problems and improving systems, then blogging can be very powerful.  It is hard to conduct research in isolation, and blogging would allow a sharing of resources and actually creates a learning community.
