What existing applications besides RSS readers? Who uses PubSub and Webfinger, and why would I want to use Atom/RSS for this type of service?

I don't see the point in this trying to be everything to everyone sort of deal.

I had a reply, but I lost it due to session shenanigans, and I don't want to write it all again.

But for RSS applications: considering they already have more than 14000 Twitter recipes, supporting IFTTT seems an excellent reason for implementing RSS. Particularly since it should take a few dozen lines of code, if that, in any decent language.
