Today we launched a new interdisciplinary journal called “Human Computation” that brings together human computation / crowdsourcing research and expertise from a variety of fields, covering a wide range of topics related to HC (Find a full list at http://hcjournal.org). 
The journal is open-access and authors pay no fees.  The editorial and advisory boards are constituted of top HC researchers from many different fields. 

Particularly in relation to the Wiki(pedia) research community, topics for submissions could include – among others: 

Applications - novel or transformative applications 
Modalities - general interaction paradigms (e.g., gaming) and related methods 
Interfaces - HCI or related human factors methods or issues 

One could for example think about the integration of human “workers” with semi-automatic vandalism detection, the interaction of editors with bots on a daily basis or one of the many other processes in Wikipedia where the actions of humans and machines are tightly interwoven. 

If you have ideas for a journal publication in this field, the journal is now accepting submissions (CFP: http://t.co/xlY7yy3zDI) and the first issue will be published in Summer 2014. 
You can find author guidelines, board members, review process documentation and instructions for submitting at http://hcjournal.org. 


Best,
