in an offline mode how would you monetise offline ad clicks? google's business model is based on ctr not cpm. are you thinking of caching ads/pages too?
I don't imagine they need to monetise this part. The offline app simply makes Gmail even better and gives those who use desktop clients one less reason to stick with them. As a result of this more people will end up using the normal online app and therefore clicking more ads.
The thing is - with the new interface, that is perfectly accessible through the browser AND makes sure your offline is in-sync why would people carry on using the regular version?
Deck is doing that somehow (caching ad impressions at least) - so it is an addressable issue. However - this app works both in online and offline mode, so my point was not really touching the offline ad problem - thanks for pointing it out.
