I would kill my wordpress blogs completely in favor of Posterous if there was a way to put advertising on their sites. Do you see that ever happening?
I know ads on websites suck, but... it's nice to have the flexibility to make a few bucks if you have a popular site. - Ben Hanten
I'd like to see Posterous offer a self-hosted version, so we can change whatever we wanted on it. What do you like about Posterous that Wordpress can't do? - Mitchell McKenna
Wordpress is capable of doing everything on Posterous, but the ease of posting is what keeps me more active. - Ben Hanten
