Like sokoloff pointed out, I think you are missing my point. I'm arguing that precisely because "senior" implies age-related status, I think many people are using it wrongly. And therefor applying time-related measurements where they are actually looking for expertise. If by "senior" you are referring to somebody who's been in the industry or on a project for a long time, I would agree. However I do not agree that that person will automatically make a good teacher, team-lead, consultant, mentor simply because he/she has been around for a while. Unfortunately I see exactly that happening time and again, and blogs discussing how "senior" they are based on how good they know JavaScript. Hence my post. Sorry if I was not clear enough in the article, I'd appreciate any suggestions on how to improve it so that it makes the point better.
