In a departure from the wiki's policy of neutrality, this content presents the personal viewpoints of LadyGeek and Barry Barnitz.

May 13, 2016 marks the eighth anniversary of the launching of The Bogleheads® Wiki. The wiki was publicly announced on May 21, 2008.[1] Our Wiki statistics page provides us with the following numerical snapshot of our wiki project as of May 9, 2016.

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

Personal Reflections

"My thanks go to Larry and Alex, for continuing to provide us with our wiki platform. Many additional thanks to administrators Peculiar Investor and Lady Geek for providing a fuller gamut of technical tools for the wiki; To wiki editors for contributions; and to our readers" --Blbarnitz 04:40, 12 May 2015 (CDT)

"Many thanks: To the wiki editors for their contributions; And to the forum members whose ideas and insight make the wiki successful. I would also like to thank Peculiar_Investor for providing technical guidance." -- LadyGeek

The wiki grew by the addition of forty-two new pages during the fiscal year. Among thematic trends, further development of pages devoted to investing in non-US domiciles continued with four new pages:

  1. Investing from Australia
  2. Investing from Belgium
  3. Investing from Germany
  4. Investing from Italy

Biographical entries, a nascent topic for the wiki, centered around two now deceased market innovators:

  1. Walter L. Morgan
  2. Nathan Most

For a complete list of new pages, refer to the 2015 - 2016 new pages box provided below.

A major upgrading of the wiki pages devoted to academics (most of whom are referenced in wiki pages) was implemented over the past year. Additions included a fuller biographical outline as well as a selection of award-winning or most cited papers.

Wiki internal programming

On December 30, 2015, we installed the Lua programming language. This installation allowed us to keep pace with Wikipedia (which had already been using Lua for its templates), as well as provide some light-weight programming power if the need arises.[note 1]

The wiki goes mobile

In recognition of our many readers with cellphones and tablets, we installed a mobile user interface on November 14, 2015. This was shortly followed by a "mobile friendly" home page on November 28, 2015.

A new home page

With a desire to attract and retain readers, we redesigned the wiki's home page to provide more "active" content. A major focus was to provide helpful content for new investors.

Taking a strong lead from Wikipedia, we introduced the new home page on April 18, 2016. The revised layout has the following new features:

  • The top of the page contains topical outlines of the wiki's major categories. Readers can find information by navigating from the topic of choice.
  • A "Getting started" section for new investors was introduced.
  • Also for new investors, Today's featured article provides introductory articles.
  • This week in financial history lists historical events which happened during the week. The complete list is in the List of historical anniversaries, which is an on-going wiki editor task. We encourage those with an interest in history to contribute events.


The main technical additions to the wiki over the past year were the implementation of the Lua scripting language and a refashioning of the wiki main page.

  1. The need arose when we created "This week in financial history" for the home page. The underlying software is here: Module:ThisWeekInFinancialHistory
