Given the level of commitment some in our little community have to walking the faint and fine line of 'canon' I wonder how they actually run their games. A good game IMO should have things altered to keep the players guessing, and most importantly it should not be afraid to rock the boat.
That said, there is an arguement for providing some level of uniformity if you are placing things in a public forum - or at least to explain the changes made, as Merric has indeed done.
I liked this, as fine a DM hook as you are likely to find.
