"In a departure from the wiki's policy of neutrality, this content presents the personal viewpoint of ________."

May 13, 2018 marks the tenth anniversary of the launching of The Bogleheads® Wiki. The wiki was publicly announced on May 21, 2008. Our Wiki statistics page provides us with the following numerical snapshot of our wiki project as of May 6, 2017.

Over the past year, growth in wiki readership spiked near the end of 2017. Historical statistics and a timeline of wiki initiatives can be found in the appendix to this report.

The year in review
The wiki grew by the addition of 18 new pages during the fiscal year. There were several pages added to cover frequently discussed concepts:
 * Robo-adviser
 * Bitcoin
 * Credit freeze

The update to US tax law drove the need for Outline of tax law changes, which may explain the spike in readership at the end of 2017.

TSP Modernization Act of 2017 was also the result of a change in US tax law.

Among thematic trends, the 529 plan section was completely revised. 529 plans by state was created as part of this update.

Our non-US editors are continuing to reflect the increased readership from Bogleheads forum members outside the US. The category of "International domiciles" was changed to Non-US domiciles in order to provide a global perspective.
 * Investing from Spain
 * Non-US investor's guide to navigating US tax traps
 * Nonresident alien's ETF domicile decision table
