I mean, that's really quite charming. She loves you!
The first time Linkedin jumped the shark for me when they suggested I add the random dude I sold a couch too on craigslist to My Professional Network. I'd used a throwaway email and only texted the dude 1x. I only randomly remembered who he was after Linkedin suggested him to me because his first and last name rhymed and when he picked up the couch I thought his name was kind of interesting. It was so weird and sketched me out quite a bit as we were in completely different industries and I had no idea how linkedin associated us.
The second time I decided I was over used linkedin was when I was a pitched a data analysis of industry trends in biopharma by a company that scraped and analyzed a bunch of my current and former coworkers linkedin profiles as well as what conferences they had recently attended. It was so creepy and invasive and accurate that I just decided I'd rather not supply my info to be a data point in some hedge fund analyst's report.
I have a shell profile but don't update because I see no benefit and have always gotten jobs without needing it.
