Yep another buzz word. But as I mentioned earlier or last month that Search engine positioning is all about social connectivity and goes far beyond the natural biology connection ( just imagine, a mom and her son ).
Or take it widely and imagine if you are in a small city like Kalmar and someone will point to two guys as liars for two years.Than come back after one year and ask everyone in that city who are the two liars, then of course evryone you ask will point directly to those two guys mentioned 3 years ago.( cappic ? )
