I do a lot of content generation in the real estate space, and a few people have recommended I try out http://dizzle.com to get more likes, retweets and +1s. It seems like you basically get points for sharing other people's stuff and you can buy shares with those points. Would these factors be deducted at all by search engines, or would this be a good way to extent the reach of my content? It loks like some people have gotten like 30 +1s just by submitting their link and giving away a few points. Thoughts?
