Thanks for reading, Justin,
Yeah, being picked up by The Pulse adds another variable to the mix that you can't rely on, but as noted in the piece, the results you had for your first two were similar to my first couple, which is relative to connection totals. Will be interesting to see your next one - and whether those numbers are maintained in future posts.
The real test, as you've noted, will be when the platform is open to all users. While the sharing algorithm is quite smart, it will be interesting to see how it's tested with a lot more content going through it. No one, not even LinkedIn, would know for sure what's going to happen - but many will be watching to see what comes next.
