Google’s Rss Aggregator , Google Reader now sports a del.icio.us link within. Apart from tagging sharing and emailing the stories you can bookmark the stories on the online bookmarking site. The funny part is that del.icio.us is owned by Yahoo Inc. which is Google one of top arch rivals ! Well Well Well … thats something to think about ! 
Have a look :
as pointed out by Kevin , thats the feed’s embedded links .. Google cant be stupid can it

The link to del.icio.us (and the Email this and View CC license links) are embedded within the feed itself and were supplied by the feed’s publisher. Reader’s links are below those links, in the grey bar starting with ‘Add star’.
Hmm really . Seriously did not know that . Thank you for the info ! will edit my article now
