I just read a review of Newz Crawler on Rick Klau
. I agree with him completely. Newz Crawler is one of the best pieces of software I've ever used, let alone the best News Feed aggregator. I am using it right now to blog this endorsement as a test of its blogger client. (uh-oh, no spell check, ok, reading news is great, but I won't be using this for blogging without spell check).
The blogging client also doesn't support titles, so I had to edit at blogger.com to add it. So, it's not a good blogging client. It is a great aggregator though. Even works on noho-missives even though I don't publish RSS (yet).
I wrote to the author and apparently, it's blogger that doesn't support titles in their API. Newz Crawler supports it for MovableType and other blogging systems.
