Robin2:
As far as I recall POWTAC's post was very short and was a useful cross-reference between similar discussions in two places.
He posted it more places than that.
I don't understand why it was removed.
It was removed because I got tired of trying to sift through his mess.
And I thought my own reply was rather longer...
Two sentences which essentially acknowledged the link.
...it really only makes sense if it is seen as a response to an attempt to set up another forum for Arduino stuff.
I disagree. The post can be construed as you adding two additional ideas to the ones you have already presented.
