A title must be able to be revised after initial writing. It seems to be not easy to set-up a title before writing a main text in usual.

Therefore, I recommend to change for this blog system to have ability to revise the title even after first saving as well. Or, provide another way to revise the title as in both the Wikipedia and Wkia system.
