@duerig@siracusa I’m not convinced that will matter much. The quantity of users is distinct from actual usage. ADN usage is still very low. Analogous to the Android/iPhone marketshare vs. people-who-are-willing-to-pay-for-things difference.
An interesting threshold is coming for app.net. Some time this month we will pass 100k users. app.net will then be a more attractive development platform than Twitter forever. Any new Twitter app will have fewer potential users than an app.net client.
