Housekeeping

Just a quick note that I did a little fall cleaning with the links on the blog.  They are now grouped into blogs I read all the time, ones I check in on every once in a while, and "old school" sites that are either infrequently or no longer updated but are still good resources. 

If you have other sites you'd like to suggest, let me know!   Comments of all stripes are always warmly received (hint, hint)....
