Last weekend, a person unknown to me announced our project on reddit:::haskell. There were about 40 comments, the most of them were positive, interested or even excited.
To answer questions and, most importantly, combat the impression that the project is not active anymore, Wulf and me decided to get us a reddit account (voxfrege).
One topic discussed more extensively was that small differences between Frege and Haskell are considered annoying for Haskell programmers. Paradoxically, those differences seem to be the more annoying the more "like Haskell" Frege is.
One key example for this is the comment syntax. I am willing to reconsider this and other topics like this as soon as possible (while there is not much code out there yet). Indeed, the opinion expressed that Frege is most interesting to "weekend/would-be Haskell programmers" who are locked with the JVM in their daily jobs, seems to be confirmed by the fact that the same announcement linked to reddit::java did not get a single comment up to now!
