Google app engine website - good idea?

Hello all, it was a possible potential client, but they were very unclear on what they wanted, where they wanted etc so I did advs I might be available when they clarified things a bit. And yeah my impression is that one person used google analytics, saw a free google website in app engine and thougth it was a great idea.

I use wp and am ok w/it. What @jeffreylees said about it.

Wouldn’t mind eventually to try appEngine but right now don’t have the time for it. And don’t want to start an unclear, unfocused project on it.
You all have a great day
