@colinwalker You're absolutely right. This will be a key tipping point for the success of new tech like micro blogging - is it simple for non-technically minded people to use and implement? You and I might be willing to play around to make things work, but most people aren't.
@desparoz It goes back to what I was saying about needing someone with significant clout (Automattic for example) to push stuff like this and implement it in core functionality.
