Fluff and spin can both make a piece of writing feel off, but they're not the same problem, and they don't call for the same fix. Fluff is empty. Spin is misleading. One is fixed by deleting; the other has to be corrected.
Fluff is thin, unfocused content with no intent behind it -- usually just careless or lazy writing. Spin is a deliberate, misleading framing of facts that are otherwise real.
Fluff: thin, no intent to mislead
Fluff just doesn't say much. Nobody is trying to trick the reader -- the writing is simply weak.
"The update is mostly fluff -- 'great momentum this quarter' with nothing specific behind it."
There's no hidden agenda here. The writer just didn't put in the specifics.
Spin: real facts, deliberately misleading framing
Spin takes something real and frames it in a way designed to create a false impression.

The underlying fact (revenue) is genuine. The framing is doing deliberate work to make a miss read as a win.
Why the distinction matters
Fluff is usually a laziness problem -- the fix is to cut it and be more specific. Spin is a trust problem -- the fix is to correct the framing, not just delete words, because deleting spin without correcting it can leave the misleading impression intact.
Wrong diagnosis: "This paragraph is fluff, let's tighten it." Right diagnosis: "This paragraph isn't fluff -- it's spin. The number is accurate, but the framing is misleading. We need to state it plainly, not just shorten it."
Calling spin "fluff" understates the problem. Fluff usually reads as careless; spin reads as intentional, and naming it correctly matters when the writing goes to a board, an investor, or a client.
The rule
Ask whether the content is simply thin with no intent behind it, or whether real facts are being deliberately framed to create a false impression. Thin-and-unintentional is fluff -- cut it. Real-but-misleadingly-framed is spin -- correct the framing, don't just trim it.
Practice scenarios
Practice choosing between fluff and spin in situations like:
- reviewing an investor update that reframes a miss as a win
- diagnosing whether a vague paragraph is careless or deliberately evasive
- deciding whether to cut a sentence or correct its framing
Useful practice phrases:
- "This is fluff -- there's nothing specific here, let's cut it."
- "This isn't fluff, it's spin -- the number is real, but the framing hides what actually happened."
- "We need to correct the framing here, not just tighten the wording."
Fluff is empty and usually careless. Spin is real content, deliberately misframed. Naming the right one changes what you fix.
