What is “comjicaito”?

My brain parses it as "communication" when reading quickly

Same first letters, the dots and the t roughly line up, apparently good enough for me

You slowed me down; the communication was successful, but suboptimal. You also kicked me down to the level of a small child struggling to assemble letters into words, distracting me from the meaning of your words.

You seem to be implying that as long as someone understands you, that's good enough, but I don't really agree with that. Do people not wish to do a good job at things in their lives? I strive to use proper grammar and spelling, not because I can't communicate without them, but because anything worth doing is worth doing well. Why settle for half-assing one's way through life just because other people can understand if they put in enough effort?

The author briefly mentions that nits break the reader's flow state. Your comjicaito only proves the road navagable—not pleasant.
