One question that we debated about was how to monitor the postings. As Stephen Colbert's now infamous Wikiality monologue reveals, not everyone appreciates the power of wiki. Not everyone will have the faith of a democratic wiki. According to Wikipedia, astroturfing:
consist[s] of a few people discreetly posing as mass numbers of activists advocating a specific cause. Supporters or employees will manipulate the degree of interest through letters to the editor, e-mails, blog posts, crossposts, trackbacks, etc. They are instructed on what to say, how to say it, where to send it, and how to make it appear that their indignation, appreciation, joy, or hate is entirely spontaneous and independent; thus being "real" emotions and concerns rather than the product of an orchestrated campaign.
There have been cases reported of astroturfing. It's a serious matter, particularly for a Health Libray Wiki which relies on both updated and accurate information. It should be taken into consideration, particularly if there are a few unruly who want to leave a legacy by giving false information to hurt the many. Can a few wiki masters constantly monitor such a wide net? That will be a challenge that we will face as we move into the information grassroots democracy. With open access, open collaboration, open authoring, open platforming, and open searching in Web 2.0 comes hurdles which we have to face bravely and heads-on.
