Professional network and platform for recruiting, B2B content, and career signaling. In this wiki it matters mainly as the social graph of work: who knows whom, what roles people have held, and how reputation gets traded through profiles and posts.
Context
LinkedIn is less like Instagram-style social media and more like a market for professional attention. That creates its own dynamics: status signals, job flow, deal flow, and a content style that often sits somewhere between personal branding and business PR. Many tech biographies and network relationships can be reconstructed through it.
Core Ideas
- Identity as CV - the profile is a curated public version of work history
- Recruiting market - LinkedIn is talent-allocation infrastructure, not only posting
- Reputation as capital - visibility and credibility become leverage for jobs, customers, and deals
- Network effects - the value grows with people and their connections
Connections
- Reid Hoffman - co-founder
- PayPal Mafia - LinkedIn appears there as one of the outcomes of the post-PayPal founder wave
- Peter Thiel - adjacent early Silicon Valley network context
