TY - Generic T1 - Social dynamics of free and open source team communications T2 - Proceedings of the IFIP Second International Conference on Open Source Systems Y1 - 2006 A1 - James Howison A1 - Inoue, Keisuke A1 - Kevin Crowston KW - FLOSS AB - This paper furthers inquiry into the social structure of free and open source software (FLOSS) teams by undertaking social network analysis across time. Contrary to expectations, we confirmed earlier findings of a wide distribution of centralizations even when examining the networks over time. The paper also provides empirical evidence that while change at the center of FLOSS projects is relatively uncommon, participation across the project communities is highly skewed, with many participants appearing for only one period. Surprisingly, large project teams are not more likely to undergo change at their centers.
