O2 / Lambda Sensor Data

[Shannen Durphey]

Careful.

1) Just because you don't like Bruce's style, doesn't mean he's not correct.

2) He's right on the money.

3) Would you like to be the recipient of incorrect information?  It could ruin a
very expensive project.  Since many people use this list as a resource, would you
agree that the list should provide good, accurate information to all?

4) Bruce has put in the time to learn what he knows, whereas most folks on the 'net
(Mr. Reeve included) are "skimming."  Bruce has a right to believe he knows what
he's talking about.  

5) Bruce's contributions to this list are substantial and good.  

6) Lose the attitude.  Don't be the defender of the nice folks.  Look for the
content in the messages.  There's valuable info to be found in Bruce's posts (and
those of _many_ other people who don't make extra time to be "nice").

7) I'm trying to help you get more out of your subscription to this list.  If this
message makes you feel you need to complain, you've missed the point.

P.S.  I have no doubt Mr. Reeve will realize that he's found some great building
blocks for his project in the resources of the list.  And if he would spend some
more time looking at work which has already been done, he won't find himself
proving that square wheels have limited use.
