I mostly flag answers that are low in quality for moderator attention, and place a comment under them saying "this answer is more of a comment". Mostly this works fine.
However, when the answer is posted by someone with insufficient reputation to comment, and I flag the answer by doing the same thing as described above, then basically the person cannot share any info.
From my point of view I think "everyone 's been there, start collecting rep if you like to participate". However, I quite often receive comments from other (experienced) users saying "The poster doesn't have enough reputation to comment". In other words, they basically say "Stop flagging newbie's answers, as they cannot comment".
Is there a consensus for this issue at CogSci? Suppose that the answer clearly is more of a comment. For example, a personal experience, or a few sentences claiming perhaps valid stuff or educated guesses, but unsupported by references.
