What type? Text and simple graphics
Where? Doesn't matter to me
Banners? Yes, if not too flashy.
Flash? No, it will conflict with the simple design that WW always had.
Animated? Same as above.
Within posts? Preferably outside...
Inbetween posts? No problem.
Left side - right side - top or bottom? Doesn't matter.
Sell them ourselves or use a network? Maybe yourselves, but using a backup network when ad inventory isn't enough and if they don't insert annoying ads.
Which network? Hum...
Does it hurt our quality? No. Most websites have ads, if done properly it won't affect.
Do you trust sites with advertising? Yes.
