I am in favor of the change. But note (as I think I mentioned in chatter early on) that when a similar change was done, it resulted in an increase in the number of duplicate postings (as people failed to find the "edit" link before finding their brower's "back" button). Or was it an opposite change was done (for one section) and the frequency of dups appeared to drop (for that section)?
The work to deal with people hitting "back" and then hitting "create" again probably needs to be raised in priority now that this change has been made.
