I concur. If we're going to list the names of who frontpaged what, it's reasonable to let them explain why they did it.
I dunno about that. The reason the fp messages started showing up was to prevent people from acting on their own nodes; front page nodes get a lot more attention and, therefore, votes. It's a simple mechanism to catch people who are tooting their own horn.
Besides, take a moment to consider what types of SOPWs get FPd, and how that'd look if the persons FPing a node had to explain it all the damn time... We'd see a dozen variations of "good node", "good question" or "well researched". This FP reason field would be little more than noise after a while.
Note that this does differ from the Approval entry for NTC -- there's a lot more variety in the reasons to consider nodes than approve them, and I'd prefer to see your reason for wanting to (eg) delete a node rather than front page it.
Also a big thanks to the gods for polishing up the Approval interface (among many, many other things)
