Comment "widget" for blog - Facebook Comments or Wordpress comments ?

If it's a true widget, it's a script. Nothing is seen by
any search engine, except the code.

And as far as adsense TOS, it would be against TOS.

Google has stated they do not want their advertisers
ads displaying on pages that allow spam comments.

Since all comments are spam, no matter what value people
think they add to any thing, why would you put
adsense on pages that allow it? Comments do not
have to have a link or viagra to be spam.

The logic is that advertisers are paying for a specific
thing. If you allow your users to add whatever they
wish, you are in effect letting your content be altered.
Advertisers should not have to keep checking to see
what you have on your website.

But, people disregard that and say, what the heck I
want to allow comments!

Google readily makes exceptions for certain types of
forums and other things done by the big boys.

This is one TOS that oodles of people ignore.

You cannot moderate spam enough. Spam is spam is spam.
A comment that says, "great post" is spam.

I think I know what you're talking about. I haven't seen that for wordpress though. When I've seen facebook-linked comments, it has been much livelier indeed, but that was on a news site with high PR.

Not sure if Paul's correct about search engines only seeing code. I guess you could test that by searching for the exact text in one of those comments.
