Hi Hovari, thanks for following us!
I try to keep the Twitter page fairly up to date and will retweet any interesting Carcassonne news that I see. So you should see it all under @Carcassonne (although much of this may be stuff that you've already seen since a lot of what I post is taken from the forums anyway).
However, I also follow a dozen or so other accounts that occasionally tweet Carcassonne news. If you look through the list of accounts followed by @Carcassonne you might find some others of interest (@CarcassonneShop is a good one but you've said you already follow this).
Hope this helps!
Dan
