Hey Prof. how do I ask people to follow my blog without being to self-serving and frankly conceited?  I mean I want to make it easier to let others know that I am out here (way out there sometimes) and I would like to invite my friends and family to read along and get a dialog started.  Of course they may not like seeing themselves in the blog but I still want to engage them in witty repartee, plus it would cut down on my phone bill...Is there a way to get them to sign up on the blog so I do not have to keep referring to these multi-colored post it notes with their e-mail addresses on them?
