Is there a name for "article doesn't at any point explain the niche jargon term the whole thing is built around?" Don't make me Google "S.M.A.R.T. attributes" just to understand what the subject of your post is even for

Also, in the first paragraph of the article there is a direct link to smartd that has a clear explanation for what smart is, no need to Google.
