at the bottom in terms of substance.
His post starts with "Who knows..."
Continues with "maybe".
Concludes with "will contribute".
Why do such posts only irritate?
1. Excessive qualifiers. Starting out with writing "who knows", betrays a high degree of uncertainty, implying the information may be speculative. It also implies the poster may be attempting to hedge his bets, allowing himself to avoid being proven wrong regardless of what happens.
2. Fundamental lack of substance. "Who knows" signals no commitment to knowledge or any particular stance. "Maybe" leaves room open for both possibilities, adding no real weight to the claim. "Will contribute" suggests only a partial causation, without bothering to explain how or why.
3. People expect opinions, especially about such important things like wars, to be backed by clear reasoning or evidence. Otherwise it seems like a person is saying something, just for the sake of saying something
