I haven't removed any backlinks. Most of our links are editorial and from users sharing content on forums. We've gotten links from some high-authority sites the past few weeks (top 1K alexa).
The site above us right now is an EMD, but the site that used to hold the #2 spot has been demoted to #7-8 depending on the query. That site is heavily SEO optimized, they have a lot of content but it's more of a information harvester - similar to eHow but targeted towards a specific niche. Looking at Alexa their traffic is falling big time, -10K over the last 3 months.
