How many times do we face situations like this in our working life when it is just not necessary.
The main thought behind wikis is to create a common knowledgebase so that everyone can work from the same page, something sorely needed in today’s world of global development, disjoint work force and hours, and the sheer amount of information flowing around. True, much of that information is ephemeral and dies almost as soon as it is read.
Major firms today use wikis to keep everyone up to date, and companies can even come to a standstill if the wiki server goes down. Wikipedia controversies show that strong rules are needed for what goes where, and who can release information publicly (within its operating context) to prevent idea wars. Once those have been resolved, it is a great way to keep going effectively.
Mashable’s short review of business wikis also includes a comment for a wiki for small business’ SocialText.
