I think I notice that every time I have to login. Isn't exactly new, is it?
I'm curious what "decent use" you used to get from it? That you used to be contacted by better fit jobs? Were you finding contract positions? Or hopping from a full time to another full time?
It has to be tough, as I imagine that most folks aren't actively looking for a job except for when they don't have one. I try and respond politely to any contacts I get, but there have been times I was overwhelmed.
