If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
Maybe that is true in many cases, but even so, it still is a bad thing to optimize for. The outside view says that most of the time, having your percentage of positive karma steadily decreasing means the quality of your comments are getting worse. If you want to be controversial and still be taken seriously, you need to signal your competence in less controversial areas.
Impacting the status quo is a fine thing to optimize for. Negative karma is a stupid thing to optimize for.
However I believe that here we are not talking about optimizing, but rather about warning signs.
