- If you are currently on the market, you should know about this series of public wikis maintained by and for jobhunters in different fields (Anthro*, Socio, History, Queer/Gender Studies, Ethnic Studies, Religious Studies, H&S Postdocs, etc. (just search for additional fields, but pay attention to year).
 Each wiki is a list of current job opportunities in the field, along with comments and updates by readers about the progress of each search.  It is essentially an anonymous community of others on the market, who post things like “I received an email for a phone interview” or “Has anybody heard anything yet?”  It’s a pretty powerful use of the public wiki format. You can register if you like, but you don’t have to – just click the blue “Edit” button at the top of each page, or a specific pencil icon to add your comments.
*note that many fields are subdivided, like Linguistic Anthro, Physical Anthro, Cultural Anthro, etc.
