You can find a number of papers on http://flosshub.org/biblio (search for license) and some of the work is summarized in review articles on FLOSS (e.g., [1]). The findings are mixed: some studies found that more restrictive licenses (i.e., GPL) led to more project popularity but others that less restrictive licenses (e.g., BSD) led to higher developer productivity. Some of the effects may be spurious, e.g., it could be that some project characteristics affect both productivity and choice of license. [1] Crowston, K., Wei K., Howison J., & Wiggins A. (2012).

What's the average number of edits per day on English Wikipedia?

by Jodi Schneider

What's the average number of edits per day on English Wikipedia? This is to frame my dissertation research -- I haven't found "edits per day" in the stats I've looked at [1][2]. -Jodi [1] http://toolserver.org/~emijrp/wikimediacounter/ [2] http://s23.org/wikistats/wikipedias_html.php PS: There are other measures of work and importance I've collected. >From the (highly recommended!) "edit sessions" paper, I get ~14,000 hours per day [3]. Alexa & Pew provide good popularity measures [4,5], and there is of course article count (4.2 million!). [3] R. Stuart Geiger and Aaron Halfaker. 2013. Using edit sessions to measure participation in Wikipedia. DOI=10.1145/2441776.2441873 http://www-users.cs.umn.edu/~halfak/publications/Using_Edit_Sessions_to_Mea… Using the ballpark 425,000 hours/month (for 2012, English Wikipedia). Wow! [4] Alexa: wikipedia.org is the world's 6th most popular website, 58.11% of traffic to English Wikipedia. http://www.alexa.com/siteinfo/wikipedia.org [5] Pew: 53% of American Internet users look for info in Wikipedia (as of May 2010). "The percentage of all American adults who use Wikipedia to look for information has increased from 25% in February 2007 to 42% in May 2010. This translates to 53% of adult internet users.

Why are users blocked on Wikipedia?

by Sumana Harihareswara

http://blog.ironholds.org/?p=31 Ironholds looked at a sample of users with one or more edits to enwiki who were blocked in 2006-2012. The short version: spam is a bigger problem than vandalism or sockpuppetry, and the spam problem is growing. -- Sumana Harihareswara Engineering Community Manager Wikimedia Foundation
