Canonical's Vice-President of Engineering, Rick Spencer: [Dash] Probably Reddit results, Askubuntu results, etc,..., cleaned up and installed by default by 14.04
Ubuntu on Air is an interesting official Ubuntu event, event expressed as a Google Hangout where Ubuntu developers are gathered in order to discuss, explain, confirm/infirm relevant up-to-date Ubuntu issues, event structured as an interview, yet users are able to directly (via text) ask questions, questions answered by the developers.
Across the latest months, Ubuntu has started a serious work on quality, quality-oriented work focused on strengthening numerous parts of Ubuntu, as well as Ubuntu as a whole (such as daily ISOs, etc).
Being interviewed via Ubuntu on Air, Canonical's Vice-President of Engineering, Rick Spencer, confirmed (minutes 16:14) the focus on the One Hundred Scopes project, exciting initiative that aims at installing a wide range and amount of lenses and scopes in Ubuntu by default.
The to-be-selected-and-installed lenses and scopes are to be (mainly) chosen from the community, meaning, there is a real possibility that scopes and lenses, already used and enjoyed by users, are to land as default in upcoming Ubuntu versions (probably the work on the One Hundred Scopes is to start in Ubuntu 13.04, yet remains to be seen when, where, how, what number, etc).
While talking about Juju, Valve, optimized drivers, not-ready-yet Wayland, etc, Rick Spencer stated that Unity is to be targeted (starting with Raring Ringtail) for more quality tests ("tests, tests, tests, tests"), performance measures, etc, consequently, probably to generate a more qualitative, fast, optimized and bug-free Unity.
