How to FIND material tagged "I Liked It"

Question:  On the Zaadz Team blog, it said that when people give out a seed for content by clicking on the “I Liked It” button, it will make that material more visible on the website.  Um, how exactly?  I can't figure out how to find material that others have marked “I Liked It.” 

I'm sure that information is out here somewhere, but I've already spent a lot of time looking for it, wading through the gazillion posts in response to the whole Seed System thing…

If anybody knows, I would really appreciate it!
