If I remember correctly, the 10 post change was due to a large amount of bots opening up their own topics purely for spam. By creating a different title for those who have not posted at least 10 times, they helped to reduce some of the spam on the boards.
Other titles may be nice, however.
(I keep forgetting to check the date of the last post. Believe me, I don't want to be "that guy who posts in dead threads".)
