The new DAU for Zynga looks like a short-term bump, probably brought about by advertising. The company may be pumping up some of its apps with new users in preparation for the launch of CityVille next week, with the intention of diverting people over to the new game. Or it could simply be benefiting from holiday week traffic, partially driven by the holiday-themed virtual goods pushes that have now become standard.

Ravenwood Fair comes in second with 222,963 new DAU, an impressive sum for a relatively new game. Some of the growth is from an ongoing recovery of users who stopped coming by during the week that the app’s viral channels were shut down.

Frontier Bonus is a light app that promises to deliver friend bonuses on FrontierVille more efficiently. A few months ago, we saw a deluge of apps like this, usually built for FarmVille; the number has now fallen, but this particular app is evidence that the trend is unlikely to die. On the other hand, individual apps like this are unlikely to survive.

Finally, Playdom also has more than one title on the list. Sorority Life and Social City both received bumps, although this may again be related to the holiday.
