How has the advice given in those two threads worked out for you?

I've been promoting one of my apps (http://www.whos-playing.com) on relevant Facebook groups, I also submitted it to Stumbleupon and I've been pushing it out to blogs & podcasts.

I've had little or no traffic from Facebook, Stumbleupon gave a good spike the day I submitted it, but since then not a single referral.

There's a little bit of interest from blogs & podcasts, but no actual coverage yet, however I admit this is an area that needs more work on my part.

There's more I can do on Facebook, and the blogs, but how as the advice you got from HN helped promote your app?
