== Improvements to Data Collection ==
* Add visit_type summation to capture usage of bookmarks and overall visitation patterns (link click, bookmark, etc)
** select count(*) as N, visit_type from moz_historyvisits group by visit_type
* Compute distribution metrics on Session Length to inform design of trail style history visutalizations
** sum of square, cubes, and 4th powers provides greater ability to characterize a distribution than min, max, mean, median
 
== Problems with Places ==
 
The following problems in the database schema, APIs, or Places in general are preventing really interesting experimentation, analysis, or user experience:
 
* Tab spawns... (fill me out!)
 
== Related Research ==
* Hartmut Obendorf, Harald Weinreich, Eelco Herder, Matthias Mayer. Web Page Revisitation Revisited: Implications of a Long-term Click-stream Study of Browser Usage in: CHI 2007
** http://vsis-www.informatik.uni-hamburg.de/publications/view.php/280
** Classifies use of history into 3 tasks: short-term revisits (backtrack or undo), medium-term (re-utilize or observe) and long-term revisits (rediscover)
** 70% of revisits occur within 1 hour
** Bookmarks trigger less than 12% of url visits
