I think the days of us hoping that Progress would become "mainstream" are long past. It is what it is.
Putting aside the sexiness... the big problem we had when we tried to sponsor a college program (or even get interns to learn on the job) is that they would search the job boards for Progress positions and see that there weren't that many jobs out there. Then they would search their other options and see many more results.
But.... Progress should still make it easier for those actually interested to get functional development copies. Free downloads with a link on the front page would be nice.
