Since about 10 days now (see this post), I am using Sauce Reader from Synop.
I had at this time a good feeling/first impression concerning the tool, and, I must say, I am quite convinced about it. Great interface, very active development team, some good ideas. You can find the last realease here (free for personal use):
For me, the best tool on MS platform at this time :-) Let’s see how the competitors will move on.
Laurent is also testing intensively the tool. His impression here, and an explanation how to configure Sauce Reader for blogging on .Text (I got really no problem to configure the Blogger part ;-).
