Posts should never become obsolete. With a little luck they'll have selected the setting that enables Blogger to inform them every time there is a new comment. Otherwise, go for it. I'm actually thinking of re-activating my old Blogger account as well. If you are happy to fiddle with the template enough you can actually develop quite an individual look and feel to the blog (which you can't do at all on Wordpress, for example, which is where I am now).

Let us all know if you decide to move!
