1) I want to facilitate dialogue between influencers and followers, not dialogue between friends. You don't need thumb-ups/downs for the later: there's not enough interest to justify that.
2) I don't want to create another social network, and there's little chance influencers sign up here anyway. Hopefully letting influencers engage through their established channels make things easier for them.
On the other hand, the fact that an important questions getting large number of thumb-ups is a statement by itself. Imagine a question for POTUS with 10k thumb-ups but got no answer from him/her. It's a headline material.
They depend on GMail.
They cannot even deliver push-notification for their iOS apps because they don't want to save your credentials on their servers.
The argument around Instapaper still stands as long as it's an independent, complete product.
