What are the best linkbuilding strategies after the latest Panda update?

I said quality didn't I!

While relevancy is cool and all sometimes there just aren't enough relevant websites to give you all of the backlinks you need to get to #1

Plus the only NOTICEABLE difference with having a relevant backlink is you may get a few targeted visitors (nothing wrong with that)

These are the results of our multiple tests the other week up until Thursday last week:

Google Penguin has a sub component called the Freshness update. This update allows brand new sites with unique and contextually relevant content posted on a regular basis to rank in Google for the keywords targeted by the sites. We regularly posted unique and relevant content on our sites, and after we posted new content, we did the following:

Google Penguin shows Google now values contextual relevance and social networks more. So, we searched for contextually relevant discussion pages, under contextually relevant sections/categories, of contextually relevant Web forums and online social networks/groups. We contributed relevant and useful info and advice in those discussion pages. We left links, anchored by relevant, diverse, non-money keywords, and these links pointed to our new contextually relevant posts in our sites, in an effort to provide viewers with relevant supplemental content with useful info and advice not found in those discussion pages and in our content contributions there. Our results?

More traffic from those online social communities. Quickly Google-indexed links in those social communities (15 hours average). Quickly Google-indexed linked pages (24 hours on average). Then, we did this:

Submitted our new posts in our sites, as is, to contextually relevant ezine networks and content syndication channels with large active publisher networks, comprised of webmasters regualrly looking for content they can publish on their contextually relevant sites, for the benefit of their viewers. Our results?

More traffic funneled from those sites. Improved page Google SERPs due to contextually relevant onpage links in contextually relevant pages under contextually relevant sections/categories of contextually relevant sites with active readership and mailing list subscriber bases. Quickly Google-indexed links in those sites. Quickly Google-indexed linked pages. Higher chances of more powerful links in those sites, since the owners of those sites and their viewrs will naturally build links pointing to our syndicated content in those sites. Then, we did this:

Searched for contextually relevant sites with large active readership, membership and mailing list subscriber bases comprised of our target viewers. Contacted the owners of those sites and negotiated guest authoring deals with them. They get relevant content with useful info and advice not published elsewhere, in exchange for onpage text links and banner ads pointing to certain contextually relevant pages of our sites. Our results?

More traffic funneled from those sites. Improved page Google SERPs due to contextually relevant onpage text links in contextually relevant guest posts under contextually relevant sections/categories of contextually relevant sites with large active readership, membership and mailing list subscriber bases, comprised of our target viewers. Quickly Google-indexed links in those sites. Quickly Google-indexed linked pages. Better chances of more powerful links in those guest posts, since the owners of those sites and their viewers will naturally build links pointing to our guest posts...

We'll be formulating new tests and implement these tests this week, to diversify our results, for additional comparative analytical data...
