Just as a humble recommendation for consideration, it would be nice to have a box in the Site Admin settings to set a default post title which would be used when users forget or neglect to add in a title for their post.
Whether someone sets it to "Untitled Post", or get sarcastic with "I forgot my post title", or whatever.
Sure would help out overall on a network, and make it easier on people visiting a site.
OK, all done. I'm off to hack this into my site. :D
