Has your reach on LinkedIn collapsed? No less a figure than Richard van de Blom says
it has and if anyone should know, it would be him. Hard to know what LinkedIn want to do with newsfeed - helping people reach audience is the best way to get original content on the feed, and suppressing reach is the best way to deter it, so recent changes to the mighty algorithm are puzzling. Seems to be what happens on social networks though, so maybe we just have to lump it.
