I am not a fan of the new software for one simple reason. If there's a way of seeing the edits other people have made, I can't find it. This means that it's incredible hard to track vandalism, for one thing. For another, it makes it infuriating and pointless to have watched pages. Why watch a page (especially if you know the page is being used to push an agenda and you are trying to make sure it remains NPOV), if you have to read through a couple of versions of a longish article to try and find the changes. Couple this with the fact that the watched list seems to only show the most recent change (or maybe that was just a bug), and I'm screwed. Real-world example: Helga (the bane of the historian) is tweaking Prussia again from various angles to make sure we understand it's innate German-ness. I go to see what those changes are, and if they are valid, or if she's tried to de-polanize something -- no diff. My watch list says this is the only change since I last checked, but the article history says Helga has made a couple of changes, and so has Eclecticology, a reasonable contributor. This is not useful.
Oh -- I also miss the link from the talk: page back to the related article.
Otherwise, it seems very nice ;-)
