This is what I'm wondering. I have profiles on all those 364 platforms for professional and social networking and of course the ultimate purpose is to use it to find a new job. Now that I have applied to a lot of PostDoc grants and subscribed to even more academic job portals I'm wondering if these non-specific websites like LinkedIn are actually any good to find a new academic job. A lot of my colleagues have profiles there as well, but I've never seen someone putting himself on the market through that. And I wonder if professors or uni HR people really use these platforms to find new folks for their faculty. Or does it look like I'm too lazy to apply for grants? Or not competitive enough? Or like I don't understand how the system works?
Is it worth to add a "I'm looking for.." section to my profile?
