Wombat...
First of all thanks for your nice comment on my other post where I explained Averages (nivlac has cited it above).
With regard to removal of Forum posts - quite frankly I find that WGT is pretty good about leaving VALID DISCUSSION - even if it "makes WGT look bad" in place in these forums if it is PRODUCTIVE.
I did not see what was deleted from this thread - but VERY OFTEN if a thread that is otherwise useful gets off track with mis-informed responses that lack understanding and it is creating an environment where the tone is becoming shrill based on faulty assumptions and conclusions the thread simply loses its usefulness. Due to a lack of understanding about AVERAGES, this is one topic where this occurs commonly. I'm not particularly allergic to WGT removing posts that have gone on a runaway train down a wrong track of bad information that might mislead other readers.
Also of course there are the instances where threads are hi-jacked or degenerate into personal bickering - which again is off-topic from the information we are seeking to exchange or learn from. I personally find it infuriating to try to read through a discussion that starts out as good solid information exchange and then as you read through it there is alot of irrelevant "clutter" of this type.
Again - each to his own BUT sometimes removal of posts makes sense.
Thanks again for your nice comment to my other post.
