No change here
I've been an active member now for several years and I haven't seen any change in activity on my end. For me, it's been business as usual. I've gotten a steady, low volume stream of emails all along the way. I get updates on contacts changes, occasional requests to endorse or notifications of endorsements, and the odd message from a contact now and then. That's about it. Certainly nothing that feels taxing. Perhaps you're more "special" to LinkedIn than you realize.
