    I think this is perfect for those people you mentioned in your final paragraph that have stopped blogging. Just because they’ve stopped, they still need to update WP or remove it to avoid some potentially serious problems.

    This might be a good way to remind them of their old blogs that they may have forgotten about.

    Good tip on the “header.php” line in the WP engine. Self-hosting a blog is more than just buying a domain name, as you point out. There’s admin work to be done, and WP makes it easy. Joomla! (good for group bloggers) has similar features, but takes more admin work than most individuals would want to bother with.
    Also, use the backup feature in WP just in case someone manages to take down your blog.
