It started with removing average karma. Now, there's no more strict karma filter. Just three options: On, Off, and First Look.
First Look, as you might imagine, is only those who are posting to LB for the first time... Which means, that about 90% of those looks fall into one of two categories: rule-breakers, OR complete shite.
Seems that things are going downhill, at least as far as overall quality is concerned.
