I was approached by a company about starting a podcast where the target audience is college students. I explained how I use to do a podcast for students called “Quiet Study Area” that had soft non distracting music to study by, and study tips. The site (ugly and simple) is still there, and I went and check my stats at Mevio and was surprised that even though the Podcast “podfaded” in October 2009, I am still getting 2000+ downloads (and this month isn't over).
This is why creating “evergreen” content (when possible) is important.
