Spamming on blogs too much (everyone) could make Wordpress eliminate the url form, with a negative impact for most of us.
We should think twice before recommending blog commenting, spamming to every newbie.
I know, i don't spam, you don't but others will do it and our honest work could be useless in the end.
Eliminating the url form for Wordpress could be the next SEO earthquake, for example the search engines, even the Wordpress owners could force them indirectly in order to eliminate as much as possible the spam, but they could find many reasons for doing this.

What do you think?
