Aaaaaand back on topic...
Thing is, back when Fable when first released it was ALL new and people would have naturally been excited about being the first one to discover hidden secrets - the fact that people are STILL searching online for Singing Sword and Sandgoose proof despite the overwhelming evidence to the contrary indicates just how involving and exciting Fable really is.
Some people will probably still keep looking for the proof just out of sheer pigheadedness

and no doubt when Fable 2 comes out we'll all be doing something similar for ages until someone finds out for certain that such and such doesn't exist. Then in four years time, people will be laughing at us for being so gullible
