Been working on Yeti as a platform of experts to share experiences and recommendations. For example, if you're starting a startup, you'll want the best advice you can find on what (not) to do. Yeti is a curation of recommendations for any topic. Avoid common mistakes and find relevant advice from others who have "been there, done that".
Sometimes we get asked how Yeti is different from Q&A sites. While we love Quora, we found a huge subset of topics can't be served through Q&A. Just look at how many blog posts there are for "10 Best Tips on Getting Traction" or "Best Marketing Tools for Startups". We feel a community driven curation of recommendations would provide more value than arbitrary blog posts.
