Googling a favourite song (we have a map of the piano) led me here. At the time I didn't quite realise it, but this has turned out to be what wiki isn't (as noted by AspieDad) - a living instrument that teaches and engages because its participants, readers, commentators and writers alike engage each other's imaginations.
I suspect this is something wiki can never be, because it is tied down in that formal format; in that it takes itself far too seriously and seeks to retain the appearance of being objective therefore stifling creativity.
What a little gem of a community :)
