I did actually get some consultancy work via my Linked-In account in 2020, so it's not completely useless. A whole half day, but that's not their fault.

I trawl through my updates occasionally and almost all are a load of corporate BS, full of "journeys" of various kinds. Also insincere gratitude to wonderful bosses and colleagues. Yuk.

I'll just agree that Premium seems absolutely pointless. I have not even tried the free trials.
