1. Consider your readers.
Every message has a cost.
If you can't write anything good, don't spread it around. Context lost is not paradise lost - but neither should one load the plate with fat and hope no one notices how small the shred of meat hiding therein. Short retorts must wait for your finest careful scribing, lest they be mere puffs of noise. Often enough, a bundle of thin reeds provides a better feast for toilers than those tossed one by one unheeded in the wind. He who speaks least often is heard most clearly, and fewer postings let your readers ponder harder on the fine and wondrous writing that expresses deep and careful thinking.
