Looks very nice!

At $20/mo there are alternatives (Zapier comes to mind) that may cover your needs as well. There's also Node-RED for those wanting something self-hosted (though it won't be as straight-forward).

The interesting thing about Pipes for me was that I could correct small things quite easy (and read my feeds later using Google Reader -oh, those were the times!-), and besides it being free it was maintained by a "familiar" site. At this point I'd rather invest my time in a tool I can control!
