Every record tells a story. Here's a few stories in my collection. Also, I've been a down-to-earth vinyl nut for decades, so if you want some record collecting advice, just ask.
Great question; the handful of followers I had at the time were lost. During the step where you change the name of your Tumblr blog to a temporary name, you are freeing up the real name of your blog, so that you can create a new blog with that name that you will import your content into. So it is a new blog, hence no followers. You might want to post notes to your followers for a few days alerting them to the move. Thanks!
