It's a well researched article, but I hate how the author did his best to frame this as some controversy of "who invented what first". Molina and Neukirchen both explicitly refuse to blame or resent Karp in any way, despite given repeated opportunities. One of the best things about the Internet is it is a medium that encourages sharing and reinvention of ideas. Google is "just" an iteration on Altavista. Hacker News is "just" a subreddit. Twitter is "just" a .plan file. But of course that misses all the years of innovation, scaling, and polish. The way Tumblr drew inspiration from a couple of personal blogs is to be praised, not looked askance at.
