A colleague (& friend) ask for my CV and I’ve drop him two lines with two URL’s, one from my obsolete web page CV (just in Spanish) and the other one from my more accurate (although not perfect) pbenavent’s LinkedIn profile.
So I get into LinkedIn in order to check how old my uncomplete my profile is. Then I start to correct it and going up & down through it I realize LinkedIn have done a simple but practical improvement.
Try it by yourself but for instance, if tag a wordpress post with linkeding tag it must appear at my LinkedIn. It let’s you enrich your profile more easily and again, Social Media is the new thing by connecting networks, professional, personal, all in all.
