Encourage Innovation - specific goals

I moved the list as it was when I came here to this discussion instead, because I agree it really needs specification of what's good with those examples, because it would be too radical to change the Wikipedia interface entirely to that of any of these:

• Measures [How will we know we have achieved the above goal?]:
  • Measure: In 2015 Wikipedia is more usable because it acts more like Microsoft Word 2010 or Google Docs or Google Wave than it does Hotmail circa 1996.
  • Measure: In 2015 Wikimedia looks more like a mix of Aardvark (the company Google bought) and an MMORPG in that it automatically suggests activities that new members would be interested in such as contributing to certain pages or parts of certain projects. This would give Wikimedia better flow and hopefully help one-time contributors become active contributors.

Personally, I don't even remember Hotmail circa 1996, and I doubt that the part of the population that is less nerdy than me could familiarize with these examples very well.

And the sentence "What about using something like this for discussing what features should be built?", I think it belongs to this discussion, so I moved it here as well. I appreciate if it could be specified exactly what parts of that discussion are applicable and useful for Wikipedia as well.
