I wouldn't mind seeing notifications to the Salon when new territories launch (or are pulled out of archives), or are sent to the archive.

As far as territories go, I do worry about losing some of my faves, and hope they can stick around. That said, some territories overlap; when I want to talk about a podcast episode, I'm likely to look to the territory it applies to (tech, books, etc) since "podcasts" is such a broad term (and iirc, it had a high posting price). Stocks and Finance overlap as well, and while I loved Charts, it's another one like Podcasts where the contents could usually apply to another territory.

@davidw has a good post looking at how territories were doing a couple of months back, and I'm hoping we'll see more data and analysis as subterritories and other changes come down the pike.
