Emailed Dr. Bob the day you sent his address...alas, no word back yet. We've got to get Press Releases out soon, so I think we may have to run without any word from him.
I am going to continue with Blogger because I think that the traffic from the existing network and the ability to rank the pages so well because they are in the existing network is a fair trade off for no title tag on your home page. Blog content changes all the time anyway, so it woudl be tough to rank a home page for anything but a super generic phrase.
I've had no problem ranking the inner pages and I have found code fixes (I pointed to them in the series) that will let you use your blog title as your page title, so things seem to work fairly well.
You can publish your blogger content into your own domain though, so if I had it to over again, I would have started with it there. All the same benefits of Blogger, but within your own domain. I'm still debating if I'm going to pull it in or leave it as is...lots of good traffic and links, but I also know that the longer I wait, the harder it will be to move.
