Stars

Organic, confidence high

Bursts

• Mar 20, 2013 to Mar 21, 2013: about 50 more stars than usual, peak 49 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.

• 4.9k stars on a repo created before February 2013 have no date, so they aren't in the chart.

Anyone can buy stars for any repo; bursts alone don't prove the owner did.

• The star history looks organic.
• 4924 stars on the creation day are undated (before 2013-02-10) and are not counted.
