I would love to see two specific proposals taken up.
One is "The Wikipedia Journal" as discussed here http://strategy.wikimedia.org/wiki/Proposal:Journal_%28A_peer-review_journal... Currently working on corporate partners for this.
And the other is a Wiki Travel Guide as per here http://meta.wikimedia.org/wiki/Wiki_Travel_Guide A great deal of discussion is occurring off line. The question is would the Wikimedia Movement be interested in being involved with developing / hosting of this sort of content. Further details of potential collaborations should be coming out in the next few weeks.
