One sentence in an interview can open a door. One sentence in a comment section can close five.

The same amount of typing can build or cost, depending on the room. A sentence in an interview is aimed at one person deciding one thing and can turn the afternoon; a sentence in a comment section is aimed at nobody in particular and stays available to everyone. The asymmetry is not a reason to be careful at all times. It is a reason to notice which sentences carry weight.

Give your attention to the few things that will be read by someone deciding something. Write those slowly. Let the rest go unposted.
