@Kroc I actually do not see Googles ads in my feed-reader and even GReader is ad-free…
When websites decide to use facebook-only, I will write and complain. If they use twitter, well that's not so much of a problem.

a) I use twitter as a filtered newsreader already (following users who post content/links I am interested in) and it works often better than my RSS-reader (I'm not using Fever)

b) If they use twitter, I can either follow their twitter-account or put the rss-feed of the twitter-account into my feed-reader.

I'm getting worried when big news sites like the NYT start dropping support for RSS or common blogging software like wordpress won't support RSS out of the box.
