A community might be larger, but then not all members will have ties to all other members. It can still be a community I believe.Joitskehttps://www.blogger.com/profile/09087406142343521335noreply@blogger.comtag:blogger.com,1999:blog-18223796.post-43769374307338680012008-07-03T16:56:00.000+02:002008-07-03T16:56:00.000+02:00The Dunbar Number is supposed to be the maximum su...The Dunbar Number is supposed to be the maximum sustainable group size for a community, above which the community fragments. That's not the same as either an individual's strong ties or weak ties.<BR/><BR/>Networks are different from communities. They are about Granovetter's weak ties and 'degrees of separation'. Granovetter's data revealed the power of having a non-redundant network, i.e. knowing people who don't know each other. Your network is what you use for answering "does anybody know..." questions.Gordiehttps://www.blogger.com/profile/11847827252511368862noreply@blogger.comtag:blogger.com,1999:blog-18223796.post-37088034452376158292008-06-25T09:04:00.000+02:002008-06-25T09:04:00.000+02:00Hi Lorraine, thanks for that observation.

But moving more online- do we go for the easy contacts with like-minded people only? could be, and is that positive or negative?Joitskehttps://www.blogger.com/profile/09087406142343521335noreply@blogger.comtag:blogger.com,1999:blog-18223796.post-26168828138072648152008-06-24T15:42:00.000+02:002008-06-24T15:42:00.000+02:00after being up until 1:30 in the morning on Crackb...after being up until 1:30 in the morning on Crackbook last night, your post caught my eye. <BR/><BR/>What strikes me is that, although we may keep many loose connections, I think that we must naturally gravitate towards certain people whose interests mesh with our own.

Maybe the definition of weak and close ties is also shifting. I'll have to read more about that. I agree you can have more weak ties online!Joitskehttps://www.blogger.com/profile/09087406142343521335noreply@blogger.comtag:blogger.com,1999:blog-18223796.post-52976786025311969112008-06-24T12:46:00.000+02:002008-06-24T12:46:00.000+02:00Maybe the 150 number has to do with "close ties" w...Maybe the 150 number has to do with "close ties" while social networking allows us to leverage what Mark Granovetter called "weak ties" (which, in some situations are more valuable).Tonyhttps://www.blogger.com/profile/07270277455710819246noreply@blogger.com
