I just tested it:
the one extra step that I can see is we will have to contribute to the master mailing list of Google so they can charge more $$$ for their ads. The first time you sign on they will make you jump thru some hoops to register with Google (just use the same names as you used with the old blogger). Google will confirm that you have added your name to their database and taken an oath that you will abide by all their rules.
They will send a confirming email to you, and a hot link to click to get back to the BeaverDam53 blog, then things look familiar, you write and post to the blog just like before.
I will be dispatching new invitations to everyone in the class of 53 that I have email addresses for. The rest will be up to you!
