 **Grammar: Avoid "the" in posts**
 - Never use "the" when "a" works instead
 - Prefer dropping articles entirely when a sentence reads clean without one
+- Example: "a permacomputer" not "the permacomputer"
 - Example: "angle brackets. closing tags. verbosity." not "the angle brackets. the closing tags. the verbosity."
 - Restructure sentences to eliminate "the" rather than forcing awkward substitutions
 
 **Grammar: Avoid verbs "to be" (is, are, was, were, be, been, being)**
 - Prefer active verbs over passive or linking constructions
+- Example: "a permacomputer outlasts its builders" not "a permacomputer is something that outlasts its builders"
 - Example: "Jason lives everywhere" not "Jason is everywhere"
 - Example: "TOML fits like a studio apartment" not "TOML is a studio apartment"
 - Contractions count: "it's" = "it is", "he's" = "he is", "that's" = "that is"
