There are a couple of people for whose posts I NEVER click on the +. There are a couple, though, who seem to generally confine their bitchiness to specific topics, so if I'm really interested in a particular thread and it doesn't seem like one likely to provoke insanity, I will click on the +. I do sometimes get burned by doing so, though.

Like I always read PDJ's HR posts and would usually click "+" when he started a NHR topic just to see what he posted, but if the insanity started flowing, usually no more clicking on the +.

I reject your reality and substitute my own.
