I don't know if this is the right place to ask this question - of course I am willing to move/delete it if requested.
I wonder if there is a site where well-known usability issues in popular software are addressed and can be voted for. So that I can
- let off steam when I am annoyed about this software again
- provide feedback to the producer of the software
- create an incentive to actually fix these issues. I reckon that it creates motivation to fix it if your software has the most voted for usability issue on a popular site..
For the first point, there is www.dreckstool.de (in German), but I can only state general discontent with a piece of software there, not address particular usability issues.
The third point is IMHO the most important one, especially for proprietory software. For Free/Open Source Software, a bug report would probably be a nicer way to ask for improvement. Most vendors of proprietory software don't let you create public bugreports, though.
If no such site exists, would you be interested in one if it was created?
