I use Vienna as my RSS feed reading. The new beta release is interesting. A while back Vienna added support to pull your feeds from Google Reader. I never used that, i pull each feed directly from the source. I didn’t use it for three reasons: 1) while I read blogs on multiple devices I partitioned the blogs per-device; 2) I never got around to it; and 3) I don’t really like the idea of an intermediary knowing all the blogs I read.
The new release has support for pulling feeds from other sources. And I’m delighted to see that there is some hope that we will see an open standard emerge for the aggregation service’s API; along with open implementations of that.
In turn this would help to allow more privacy around the aggregation service. That’s a hard problem, but I have a sketch of a possible solution.
