Assume that a web sales transaction will take a half hour of your time. Therefore, don’t bother selling any item that’s worth less than a half hour of your time. Give it away (if you can do so at no cost) or throw it away (if you can’t). – Matthew Butterick
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
