i should be more clear - github has the potential to be a real threat to wikipedia in the long run. a group of hive minded individuals developing code together with powerful tools, tools more powerful than web text boxes. with a stretch of the imagination. github could start projects not only related to software projects but projects such as a repository for all human knowledge.
is this a form of censorship or am i tilting at windmills?
The article was not deleted because Wikipedians think GitHub isn't notable, much less that because they're somehow trying to suppress knowledge of it. They deleted it because (as far as I can tell) it contained no information about Tom Preston-Werner beyond the fact that he created GitHub and Gravatar, and that single fact is already mentioned on both companies' pages. I don't see any conspiracy here, especially given the existence of this: https://github.com/wikimedia
