The Periodic Table of Professional Networks

SERIES NTWK
YEAR 2026 Q2
STATE informational
01 // PREMISE
Four well-known platforms now dominate the professional networking category. We classify each like an element: by group, mass, and bonding properties.
02 // METHOD
Each element belongs to a chemical group: Core, Job, Startup, or Real-World. Mass values reflect platform scale; not all elements bond well alone.
03 // CONCLUSION
Most professionals combine elements. Four-element compounds outperform single-element solutions on essentially every measure.
