I published my first blog post yesterday on tumblr. But tumblr was weird, and I couldn't get it to send notices of my new posts to my facebook newsfeed. Also, the URL for my blog was unreachable by anybody without a tumblr account.
Trying to understand and fix these problems, I accidentally deleted my post, which I had worked very hard on. I felt despair and deleted my account. Before letting me go, tumblr offered me a link to tell them how I thought they had messed up. I hit the link and it took me to a page for creating a new account. Q-E-D.
I have a fairly low level of confidence that Google will be any better, but there seem to be plenty of free blog hosts, so I'll just keep trying them until I find one for which the design and instructions have not been written for people who already know how to do it.
