suboptimal systems, tools and concepts that have too high of a switching cost to be replaced

• conventional math notation
• the gregorian calendar
• the decimal positional numeral system
• the imperial system of units
• the markdown language
• ANSI paper sizes (Letter, Legal, Tabloid...)
• the qwerty layout
• bash and other shell languages

examples superior alternatives

• my math notation
• the international system of units
• better markdown when I get around to finishing it
• iso 216 paper sizes
• distance pair kinship
• the dvorak layout
