I, Owen Earl, supreme dictator of the Tin Can Phone Club, herby decree the new character limit to be 666 characters, in honor of satan, may god have mercy on him. Hereby rendering the character limit aspect of this post invalid.
In all seriousness, the rules of the Tin Can Phone Club should benefit us— that's part of the point of running our own social media site. If there are rules or functionalities that feel restrictive we can and should change them!
Personally I think posts benefit from being on the shorter side. My feeling is if we have a lot to say we can link to an outside source. Maybe that can be a cultural thing and not technical limitation.
