These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Fireball 20 XL
Badass Decay: Happens to Sephiroth in The Rogues Gallery. He even complains about it himself.
Wil used to have an "idiots" page where he made fun of people who asked him Gannon Bannable questions in emails. One in particular is that there is no Chaos Diamonds 1 or 2. It's called Chaos Diamonds 3 because there are three Chaos Diamonds in the story.
OMA, meanwhile, will Gannon Ban anyone who asks what song Shadow was listening to in his short Flash movie Sonic Stereo. He got so many people emailing him asking (for the record, the song is "This Machine" by Julien-K, Team Dark's theme in Sonic Heroes) that it actually became a running joke on the site, and was even given a reference in the first episode of Psy's Sonic Bastardized Sonic OVA fandub.
