App.net's statement: "Trust us. We'll charge you so you don't have to see ads."
Ello's statement: "Trust us, we won't show you ads."
The statement we deserve is akin to email's promise: you don't have to trust us; competing providers keep the ecosystem honest. (And the service is federated so you can connect with friends on other services)
Ello strikes me as another silo'd service. What happened to the dream of building "big" services that outlast a single company or team? The 30 year lifespan of SMTP+email, the 20 year life of HTTP, the 10 year life of XMPP.
Today we have users voting with their feet: eg I use Twitter/I stopped using Twitter after they pissed off the developer community.
Wouldn't it be great if we built services where the decision isn't use/don't use, more, my identity follows me to the best service provider (heh, like email!)?
The real statement should be: "you don't have to trust us, this is a protocol: - developers can write services against it, users can choose the developers service they like the best. And when that service goes pop, or the developer moves onto a new project, you are not stranded - just switch providers.
(disclaimer: this stuff makes me angry and we're trying to solve it at Buddycloud Towers)
