There's a curious but understandable discrepancy between the earliest parts and all later—most?—parts of this story. The earliest parts have a similar audience-participation to the MSPA stories that preceded it, with the audience directly inserted into the story (as in this page). All but those earliest parts, however, try to tell a self-contained story wherein all the elements are meant to be a believable part of the characters' world. I think these early audience-participation parts are explained away as being from the Wayward Vagabond's perspective, but I'm pretty sure that was not the original intention.
It definitely wasn't the original intention. I imagine that with the amount of attention it got, the suggestion quality fucking tanked and that half of the suggestions were stupidly lewd in nature.
