Isn’t this the eternal question? *grins* but I do have an answer this time - if I scope the question a little that is.  I am blogging here because someone who I have never met was kind enough to reply to a post of mine on a work forum when I thought I was just shouting into the cybervoid.  As I was telling her about how I was using blogs with my students, I found myself saying - I guess I should blog about this myself - and so here I am.  Thank you, Anne!
