Good read and comments everyone...
Just thought I'd throw my .05 in here on the 'why not copy these?' question.
(Nickles are the new pennies, you know...)
why there is no another twitter or facebook?
Because those would take WORK, Technical Skill and Time to reproduce, unlike content which can easily be scraped and distributed to 10, 100, 1000 sites in a matter of minutes...
Which is more cost effective? Spending the time, energy, money to reproduce a site which requires a high degree of technical skill OR swiping the content someone else has created and slapping your own AdSense code on it in a matter of minutes.
