Hello, been using social media for both some great promoting and "dofollow" inbound links for both marketing and improving my sites SEO.. However, it appears that the big ones such as digg (digg.com) and mixx is based on how many friends you also have that are "digging" or giving a thumbs up on the sites you bookmark or write a short summary about. It appears, that those that have the most friends, tend to get the highest seo benefit, as their friends take the time to click on and either digg it or not.. I'm looking for those onlne with a mutual interest in being social media friends, and take the time to read each others short posts a few times a month. Those that have the most friends, seem to reap the most benefit out of this.. Anyone looking for more social media friends.. You can contact me at: steve453us@yahoo.com
