One reason why trackbacks are better than commenting
Just realised this when about to comment on someone’s site.
I leave my tracks at the guy’s place, IP address (using which maybe you could find out my country of residence etc.), how did I reach that site, what browser am I using etc. etc.
When I comment on my own personal website, such as https://nullbit.wordpress.com, I might leave tracks that will be known only to the people behind WordPress.com but no one else.
