Now that you mentioned having a fixed length stipulated by the user's settings... It occured to me that something would have to be done with all of the previous posts (aprox. 16,000?) that are already on the database, in case the descriptive title suggestion were implemented. The lousy thing (in a good way) about our liberty to suggest stuff in PerlMonks is that we know this site is live. I can imagine the nightmares vroom must have every time we come up with an idea like this.

Changing code? No problem.
Changing the database schema.. Whoa!

Even if some work needs to be done in order to allow length, rather than a descriptive field, I'd rather go with length myself.

Good call!
