* CreatorBacklash: Peter Paltridge won't avoid admitting his discontent with some of his old, discontinued series, such as ''Riot Act'' and ''Marin Meadow'' .
* MissingEpisode: Several of the oldest banners got deleted to save space.
* OldShame: In its formative years, the site contained no archive. Some cartoons were literally up for only one week and then banished forever. The practice was originally due to limited storage space (it began as a [=GeoCities=] site) but was continued until 2006 as a means of quality control (anything Peter Paltridge didn't regret making was given a position in a selective archive section). Most of the pre-2006 works are still offline, but lately they have turned up in book collections.
** One discontinued series, ''Guava Guava'', still has a few comics posted at platypuscomix.net, including the second part of "Raiders of the Lost Arc". However, Paltridge divided them among the Variety and Kristmas Klassics sections, as opposed to giving ''Guava Guava'' its own menu and spot on the homepage.
* ViralMarketing:
** Some of the banners displayed in Fall and Winter of 2010 have [[http://platypuscomix.net/top162.jpg the number pi]] [[http://platypuscomix.net/top166.gif displayed]] for reasons that didn't seem very clear until New Year's Day 2011, when Paltridge released the first ''Princess Pi'' comic.
** During the week of April 15-21, 2012, the banner featured a working countdown to midnight April 23 ET, at which time Peter Paltridge would make "the most important announcement in Platypus Comix history." Paltridge [[http://platypuscomix.net/top195.gif extended the countdown]], then [[http://platypuscomix.net/top194.jpg shortened it]], [[http://www.platypuscomix.net/top196.jpg then]] [[http://www.platypuscomix.net/projects/bang.html revealed]] that he plans to collect stories and comics for an independent publication: ''[[http://www.bangpdx.com/ BANG! The Entertainment Paper]]''.
* WhatCouldHaveBeen:
** Paltridge reportedly planned a "True Believers" sequel called "A Very Merry Marvel Christmas Special". However, he ended up deciding his script for this comic seemed like too comedic a follow-up.
** Paltridge posted some descriptions of [[http://www.toonzone.net/forums/showthread.php?203624-quot-2008-Character-Strike-quot-Talkback&p=2809729#post2809729 deleted scenes]] from "True Believers" after finishing the final pages.
** Paltridge's DeviantArt page includes sketches and synopses for two abandoned ideas he had for flagship comics: ''[[http://torquesmacky.deviantart.com/gallery/?offset=72#/d1lrhzf Mackenzie, the Magician's Daughter]]'', and ''[[http://torquesmacky.deviantart.com/art/Johnny-Redshirt-285488887?q=gallery%3Atorquesmacky%2F8103475&qo=3 Johnny Redshirt]]''. They both got rejected in favor of ''Webcomic/PrincessPi''.
