If there are MULTIPLE views for a type of data, an infinite scroll consumer is a valid 'secondary' view.
In the case of Twitter I think I'd find it WAY more useful to have a view that breaks things down by month or week, with the old items gaining permanent addresses on such pages, and actions that break out of the infinite scroll re-directing to those permanent places.
