How this happens or who does it is obviously a larger and more complex conversation however it is better then involving innocent animals.
How is it that trivial $#*! gets voted and has a string of comments I can not explain, however Planet MySQL should have practical MySQL related content. I would vote for the front page and RSS feed to show only moderated content, and content that did not pass the cut (and there is a lot of this) can be available on a less important page if necessary.
Rather then complaining like many open source communities, let us propose a way to improve the system we use.
