I’m mostly with Dr. Drang on the current feed-sync shakeup. I’ve been happy with Underscore David Smith’s Feed Wrangler as a back-end and iPhone app, but I don’t use its web interface — I prefer native Mac clients, so my setup is still in flux.
For about a month, I’ve been using NetNewsWire 3 for Mac in parallel with Feed Wrangler for iPhone (and just not reading feeds on iPad), which has given me a fresh taste of what it’s like not having sync between platforms. While it’s not as awful as I expected, there’s no good reason to keep doing it.
ReadKit for Mac just added Feed Wrangler support, so I’m trying that out now. Reeder for iPhone will get it shortly, and Mr. Reader for iPad already supports it.
