Very strange indeed

Allright I submitted the post on the Russian-Koreans below to the History Carnival. Like last time I got an e-mail response in less than a day. Unlike last time it was not the automatic rejection I was expecting due to my being on some sort of History Carnival black list. Instead it merely thanked me for my submission. It looked very similar to the response I got back from the Teaching Carnival. I am still pretty sure that my post on the Russian-Koreans will not be linked by the History Carnival. Their track record and the very similar profiles of all the hosts militates against it. But, I am not sure why carnival hosts have started thanking me for my submissions? Is this some sort of new policy? It is very strange indeed.
