There is no etiquette rule that is against posting sightings. In fact, in most other regions (if you look) and amongst us Minnesotans at least, it is a very normal post, and every so often, it is another CEG'er that has been seen.
It is also a common post topic in other car forum's local areas I have visited. The local RX-7 club even prints business cards to place on spotted RX-7's to drum up club membership, giving a membership discount to the person doing the referral.
I do not understand either why you are annoyed with the posts, Davo, but I personally like to see the enthusiasm spilling over into shouting out to others.
