In a location far more often read than any wine or culinary forum it is written: "Render unto Caesar what is Caesar's and unto the Lord's what is the Lord's". Updating that quote a bit - render unto Robin what is Robin's and unto Rogov what is Rogov's.
I'm sure that a great many posts will be of interest to readers of both Robin's and my own wine forums. In general, I would suggest posting on whichever seems most appropriate and which is most a part of our habits. In specific cases (e.g. Israeli wines, kosher wines, tasting notes, questions or requests to me) on Rogov's place. In cases of anything we consider of supreme importance, posting where one is most comfortable and then placing a link to the post on the "other side of the board".
