I only use one news aggregator these days, NetNewsWire. Brent Simmons has just released another beta of the 1.0.4 version. This is the pay version of NNW. There is still NetNewsWire Lite which is free.

The number of features that have been packed into this beta is truly astounding. The biggest is probably that NNW has switched over to Web Kit, so all the content encoded feeds render very nicely. Aaron Swartz's htmlDiff has been integrated. It's faster. It has more keyboard shortcuts than you can shake a 17" Powerbook at. It even has gzip support for servers that can send out gzip compressed files.

One of the best things is that development is fairly open. By that I mean that Brent is willing to listen to people and you can see from his release notes where ideas come from and you almost get a feel for how fast they get integrated into NNW.

Update: The final 1.0.4 version (3.0 MB) is out.
