The only thing I'm annoyed about with this announcement is the title. SO Jobs isn't coming back, this isn't SO Jobs. If you want a partnership with indeedIndeed and think that will be profitable, great! but this isn't what SO Jobs was. It isn't different from every other job search network (it's literally just phoned in from another job search network!)
I don't really understand yet why iI would use this over just going to indeed. Surely I'd rather see all of the job listings relevant to my searches rather than just the ones SO has deemed worthy of my viewing.
