Because you look more stylish that way.
More seriously, in the IMHO thread, “I’m not anti-guns. I’m anti-bulletholes in my patients”, at post 57, Asimovian told The Lurking Horror not to troll.
At post 58, The Lurking Horror apologised, but asked if Asimovian was speaking as a moderator.
At post 64, Asimovian said he was, but acknowledged that the “moderator” description didn’t always show up on mobile devices.
All very polite and civilised on both sides, but I think it would always be helpful if a Mod expressly states if they’re acting as a Mod, or as a poster, especially since the “moderator” descriptor doesn’t show up on mobile platforms.
A newbie might not realise they’re being given a gentle nudge by a Mod, and old posters may not always appreciate that the Mod is posting as a Mod, not just as a garden variety poster.
There’s several classic styles of Mod hat to choose from, depending on each Mod’s personal style sense:
“Mod hat on”;
“The Moderator Clears His Throat”; or, in extreme cases,
“I am the fucking hall monitor!”;
followed by “No warning given” when it’s just a gentle Mod reminder of the rules.
Just a thought.
