Hi - First time 'poster!' - I am just having a play about with NodeXL at the minute and am wondering about the position of nodes within the graph (currently set on Fruchterman-Reingold). I am splitting the graphs from certain Twitter accounts into three different formats: one for 'followers/following,' one for 'mentions,' and one for 'replies.' The graphs are circular, why do some nodes appear closer to the main user in the centre than others? I gather that for 'followers/following' a mutual follower/following relationship corresponds to why people appear closer to the main user in the centre, but how are their positions determined?
Cheers,
Andy

Hello, Andy:
That book was written long before Twitter instituted rate limits, which place heavy restrictions on how quickly NodeXL (and similar programs) can get data from Twitter. For example, Twitter will provide follower or following information for only one person per minute, so if you have a network of 3,000 people, it would take longer than two days to get follower information for all of them, or four days to get follower _and_ following information. We didn't consider that practical, especially when some people were attempting to wait that long and getting unceremoniously disconnected by Twitter in the process, and so we removed that feature from NodeXL.
Short answer: You cannot do what you want to do.
