Found it somewhat interesting since I recently started using Bitbucket, another hosted DVCS site.
Apply an appropriate level of bogofiltering for it being from Wired and for the gushing by fans, though ;)
Also see Linus's comments in the article. Linus created Git, on which Github is based.
As a side note, check Github Gists, which are something like pastebins, and useful.
