Intro vs. Summary

I\'ve gotten an increasing number of requests to treat the intro text of an article (what you see on index.php) as a summary and not an intro. The idea is the intro text would then become any arbitrary text to encourage someone to click \'read more\'. Once they click read more, instead of seeing the bodytext appended to the end of the intro, they would see just the body text.

What\'s your opinion? Leave it as is or make it a summary? Maybe allow both via some configuration setting? Let me know.
