I’m looking forward to poking at the raw data. I’m wondering what the wiki population was, and whether it was dominated by wikias, and to what extent wikia might generalise to other wikis. I suspect wikia has its own special kind of problems and behaviors. Several large wikis there have reached a fork point and split out from wikia, and when that happens, the old one doesn’t go away. So that might skew any general results.

It needs pre-indexing (duc index /path) separately from browsing. There’s (at least) three front-ends for browsing the resulting database: via ncurses, X/GUI, or a web front-end.
