Successful open communities must occasionally interact with closed worlds. For example, Wikipedia's openness and transparency sometimes conflict with their obligations to be responsive to the law (e.g., defamation, copyright, and human safety). Such is a consequence of becoming a notable and established institution.
A new source of tension is the "professionalization" of Wikipedia administration -- a move I otherwise commend. It appears professional marketers were asked to develop a marketing/fundraising campaign, yielding the "WIKIPEDIA FOREVER" slogan. Some Wikipedians feel this is inappropriate, arrogant, and loud -- a sentiment with which I agree. A more wiki-typical discussion of appropriate slogans can be found here.
