Fragmentation

Fragmentation in the wikisphere is the tendency for there to be many wikis with overlapping content. Sometimes this occurs by accident, due to people's lack of awareness of other wikis' existence, which leads to them to establish duplicative new wikis. Other times it happens when disgruntled users break away from existing wikis to form their own competing wiki. Fragmentation is sometimes considered good, in that it allows for experimentation with different schemes of organization, governance, presentation, etc. It is sometimes consider bad, in that it increases the amount of time users have to spend checking various watchlists and otherwise performing the same work on multiple wikis.
