See e.g. here. The answer does not mention anything the other answers didn't mention 9 hours before, except for a (indeed useful) link. Shouldn't this rather be a comment on one of the answers?


If the answer adds new information - in this case a link - then there's nothing wrong with it. If the link is useful up-vote, if not down-vote (if you really feel strongly about it). A comment asking for the relevant information from the link to be quoted might be in order, but that depends on how much would have to be quoted.

If it's from a new user (one with less than 50 rep) then they can't comment, so in these cases I'd leave a comment but not do anything more. After all down-voting would just postpone the time at which they could use the site properly.

  • In this case the user has rep to comment, and his answer consists of a link to a site which just states what another answer has already quoted from a manpage. I don't know if this additional link is useful, though it certainly isn't a reason for a downvote. The question is rather, should such answers be commented to encourage users putting minor additions as comments to existing answers or just leave it as is, which will probably not gain any upvotes anyway. – Tobias Kienzler Jul 13 '10 at 11:11

    @Tobias - in that case add a comment to that effect. – ChrisF Jul 13 '10 at 11:35

I've seen better examples for those oneliners. But if they`re bad enough, they get their downvotes or at least comments. The referenced example is instead fine to me. I'm not a unix crack and my first impression was, that this is somehow different answer to the question. And there's a link that might help the OP more than the other answers...

I've seen people leaving answers as comments but to my experience those are mainly members with high reputation who just don't want to get upvotes for simple google or tutorial links.
