What isn't clear from the raw data is why that might be the case, but I have a few ideas about that:
- New features - the HR training schedule and sign-ups and a look-up page for our contacts database are now both on the wiki, along with the staff directory (via a frame of the existing non-wiki page). These are high-demand services, so having them on the wiki drives traffic to it.
- Critical mass - the wiki has now been in place for several months, so perhaps people have finally become comfortable enough with it that they turn to it as the default place to go looking for information.
- Front page - the page view stats for the main page of the wiki show the most dramatic change, more than doubling in a single month. I suspect that we have finally gotten people to change their bookmarked links so they're going automatically to the new intranet home page instead of the old. In fact, the total increase in page views can be almost entirely accounted for by the number of additional front page hits beyond the expected increase.
