My friend Vanessa just started blogging to help facilitate conversations with other people working with people with special needs.  This field is really important to her... as her dad was diagnosed with MS over 25 years ago.   If anyone has any tips for other bloggers in this field she should connect with or how to approach this kind of a blog, please leave a comment on her site.   Good luck, Vanessa!  Its obviously a very worthwhile endeavor.
