I still think there's an opportunity for something better-than-Twitter, IRC, RSS in the mobile space. Twitter is SMS mobile, but has what is honestly a shitty client experience on (everything, but especially) mobile.

I wish someone would do something with the same initial goals as Diaspora (self-control, etc.), but focused on mobile, with ease of use on mobile as the goal. Snap Chat is kind of a step in that direction, but I'd rather have something where users got to explore the continuum of ephemeral stuff (like Snap Chat) to semi-permanent (like Twitter) to more permanent (like a blog, designed to be referenced in the future) to really permanent (publishing).

I feel like this is a case of the tech savy being somewhat removed from the majority of the web's consumer base. Honestly, I've had a surprisingly large amount of trouble explaining something like IRC/RSS to someone like my parents or my non-techy friends. I try to explain that IRC is just like any other chat room, but honestly it's incredibly scary and unattractive to most people.

When Firefox 4, the first version without the button, was released, Twitter had already 200M users.
