What you're seeing is, as mentioned already, the result of the Unified Community Platform update. All new wikis have been transferred, and to my knowledge, wikis that have volunteered have also been in the process. At some point, all wikis will be converted.

As long as you're using a supported browser, hopefully you can expect it to become better.

The best way to see what's going to happen is through blogs that MisterWoodhouse has posted recently about the update.

Hope this helped!
