Is it a duplicate content ?

Hi 

Please check this link : http : // www . speedguide . net/news/yahoo-acquires-email-management-app-xobni-5252

it's a post where the admin just write the first 200-300 words and then insert the "read more here" which links to the original post

This make the website active as the admin always add new content but is this not against google rules as it's a duplicate content ??

Can you tell me the name of this strategy ?

Is this really work to make the website active ??

In that example, about 1/3 of what was written was verbatim from the original site.  As an individual case, it's not bad and you may possibly get by with doing that without ever being filtered or penalized.  I'd say to always keep the exact duplicated content to a minimum and add as much of your own original thoughts into each comment as possible.
