Twitter spider

Spider friends pages for a list of named twitter accounts. e.g. [login to view URL] [login to view URL] ... [login to view URL] The spider will output a simple Pajek .net format file where vertices (named accounts) are stored as <id> "<label>" and edges are stored as: <from_id> <to_id> <weight> (weight is a count of the number of links between vertices -- in this instance weight should ALWAYS be 1) Here is an example format: *vertices <# of vertices> 1 "http://twitter.com/briansolis" 2 "http://twitter.com/another" 3 "http://twitter.com/another" *edges 1 2 1 1 3 1 2 3 1 May not need MySQL back end -- depends on memory handling. There will be two other closely related projects that follow this one. A satisfactory result will lead to automatic selection for the next project(s) Spider can run from the command line (I use Mac OS X by preference, and PREFER cross-platform tools)
