Well, if there's on thing Technorati is currently great for, it's to find out whose scraping your content.
I dropped a note to a friend last week about 9 sites that were literally picking up each one of my posts (here and elsewhere) and evidently auto-inserting a different author's name, and making slight modifications to the content..., I suppose to cover copyright issues.
I also noticed intense scraping of TechMeMe and others.
Imitation is the sincerest form of flattery? Here we go again?
Technorati's needed a little 'tune-up' for some time so before they fix this (each scrape adds to your authority??!!), you may want to head over and see whose 'borrowing' your stuff.
