I actually don't like this "vanity" thing.
The name of the author of a post is given clearly
enough, whether in the Newest Nodes list or
in the threads, and I frankly I find it quite obnoxious
to get the name once again in the title.
Now despite being French I would not recommend parading
in the streets with the heads of the those guys on stakes but still,
I do not think such an option would enhance the site.
Update: if the problem is that posts are hard
to distinguish in the serach results, then let's just
add the name of the author to the search results instead,
so both arturo and I are happy.
