So would contest entry tweets and retweets be kosher or no? A lot of bloggers in my niche do this (tweet my site link for an extra contest entry or follow my twitter account for an extra entry or link to my page from your facebook account for an extra entry or friend my facebook page...etc., etc.) and I never got on that bandwagon because my perception is that those are "incentivized" links that will burn my site in the end...but my perception isn't what matters, it's google's that counts.
Good idea to run with that or no? Thoughts?
