There's a contradiction here somewhere! Google's proposal is about search
results -- they do not propose to solve the problem of comment spam, they
only propose to stop rewarding comment spammers. And the way they are going
to stop rewarding them is by treating every link in a comment as if it was

So I don't think we need to say again that comment spam is undesirable -- we
all agree on that.

Am I missing something in what you are saying here, Nicholas, since there
seems to be a contradiction again? Of *course* you want the search engines
to follow the links -- that's my point -- but with Google's proposal they
will no longer follow the links. That's across the board, in all comments --
you the blog owner will have no control over it.

Not true. The problem is caused by:

 * blog software that allows anyone to post;

 * blog owners that don't strip out garbage;

 * search software that cannot tell the difference
   between a link made by the blog owner and a link
   made by a person leaving a comment.

I don't say they're easy problems to solve, but they are certainly not
problems to run away from. And whichever way you look at it, the "nofollow"
proposal does not solve the problem of content spam.
