Principle
Use weak ties as opportunity channels, not a connection-count target
A useful network is not a contest between best friends and strangers.
When it fits
- Professional networking has collapsed into follower counts, connection requests or only talking to close colleagues.
When to avoid it
- The LinkedIn experiments do not prove that manually adding weak ties causes a better career outcome for every person or industry. Strong ties remain important.
Why it matters
Keep some real professional contact beyond the close circle: acquaintances, former collaborators, peers from adjacent teams and people met through shared work. Large LinkedIn experiments found that weaker ties can increase job mobility, but the relationship was nonlinear and differed by industry and tie measure. The practical lesson is diversification, not maximum distance or maximum volume.
An example
Instead of adding hundreds of strangers, keep light contact with former project peers, specialists in adjacent domains and people you met through real technical discussions.
Check your result
The network contains several credible channels to information and opportunities outside the closest circle without requiring mass outreach.
Keep this limit in mind
- The LinkedIn experiments do not prove that manually adding weak ties causes a better career outcome for every person or industry. Strong ties remain important.

Evidence and sources
Large randomized LinkedIn experiments found that weaker ties could increase job mobility, but the relationship was nonlinear and varied by tie measure and industry.
The experiments manipulated platform recommendations and do not justify maximizing connection count, spamming strangers or assuming weak ties outperform strong ties in every industry.
