I've given a few invited talks that I have up on SlideShare and Youtube that I'd love to showcase on LinkedIn. However, there doesn't seem to be a good place to put these sorts of things. The closest I can see is "publications", but this isn't a publication; it's a presentation. Is there something I'm missing? Is there a "right" way to do this that would make the most sense to the person viewing the profile page?
There's no way to add them now but you can still use the Projects or the Publications sections to do it. Many have requested this since years ago (1, 2, 3), including me, but sadly LinkedIn is just ignoring this lacking feature.
