When I read that, I laughed, because here’s the irony—on this site, on my own personal weblog, Radio UserLand rather than NetNewsWire is the most-used aggregator.
(Check out the referers page.)
But you know what? It’s all good.
Though Radio and NetNewsWire have some overlapping functionality, the two apps can also be seen as complementary. I plan to develop this further in the pro version, which will be scriptable and will include the ability to publish to Radio weblogs.
