Thanks for bringing up this point - I agree Eric - competitive positioning can help you determine value that you bring to the table that your competitors dont.  I'm all for it.  Neilsen does some reports that provide awareness, likelihood to recommend, sentiment and other insightsfor your site/brand and your competitors. You can also pull some of that type of insight out of social listening platforms like NetBase, SM2, Radian6, Dow Jones, Nielsen, and so many others.  I've even done some hacked compeitove sentiment comprisons before using Search: searching for [brand or feature] + "like", "love", hate", "wish" etc. 
I’ve just started blogging and there’s a ton of useful information here. I was wondering how to use reddit and you cleared that up for me, as well as when to post to social media. Quora I’m going to check out as I’ve never heard of them-thank you! In your opinion would you also deal with any of the free traffic generators to have people come and engage, or would you skip that step? Would you use meta tags, and if yes how? Thank you for your time and I look forward to hearing from you!
Great post. I know most of the stuff experienced people read and think “I know that already”… but actually lots of things we tend to forget even though we know them. So its always good to read those. What I liked most was the broken link solution. Not only to create a substitute for the broken link but actually going beyond that. I know some people do this as SEO technique but its actually also useful for the internet as you repair those broken links that others find somewhere else.
