The above was generated by using scrapy to crawl TvTropes, cachine the
pages in a SQLite database, extracting the shout outs with Beautiful Soup,
storing those links in another table in the database, and then using
networkx to calculate the page rank of each work, which serves as a convenient measure
of influence.
The user base of TvTropes skews young and geeky so this should be used
as merely an entertaining approximation of the actual influence of
various works of pop culture.
