Number of speakers and participation

Is poetry knowledge? You sure can't put poetry in en.wikipedia. Not even close. 

There is a lot of poetry in Wikisource. Wikipedia is not the only Wikimedia project and as Wikipedia comes closer to being completed other projects will get more attention - as commons has recently.

Possible future Wikimedia projects which would never have a place in Wikipedia:

• Original research - a wikimedia archive of new field recordings
• Non-notable facts - a wikimedia database of facts harvested from info boxes and usable by any language - could include items which are not notable enough to each get their own article
• Not neutral POV - Wikisource is already archiving lots of opinionated stuff.
