• algorithms/README - copyright date is wrong
• centrality README - make the image a little smaller (use the size tags)
• for each of the sub-READMEs - you can drop the “RAPIDS notebooks” portion
• Betweenness notebook - karate image broken
• Betweenness - might be better to drop the “print top score” function and just use the “sort + head” call that is done next
• Katz - same as above
• Katz - the the Numpy version still needed?
