One of the things I’ve been thinking about and watching for is how Social Spaces change depending on the size of the community. For example, LinkedIn’s news has the comment field at the top (it adds a second one at the bottom once there are three comments). This is fine when you have a small community leaving very few comments. However, if you had a slashdot sized community, this would encourage idiots to post before they read what other’s said.
Too often we treat all practices as if the fit all communities, but the fact is size matters. For instance, Joshua’s favorite example of the top diggers page, recently removed. What motivated folks at the beginning became a gamed liability once they got big. Much as we are reluctant to change UI’s and remove features, there is a reasonable strategy for it….
