Intro — "I'm an introverted developer. Do I really have to network?"

Introverted Senior developer:

"I'm more comfortable alone. Meetups drain me. But everyone keeps saying 'you have to network to build a career.'"

Answer: Yes, you should — and introverts absolutely can. Just not the extroverted way. Do it the introvert's way.

Mark Granovetter's 1973 paper The Strength of Weak Ties:

In other words: 100 shallow relationships beat 10 deep ones for career purposes.

This post covers:

  1. The science of networking — Granovetter, Dunbar
  2. Strategies for introverted developers — 1:1, asynchronous
  3. LinkedIn/Twitter/GitHub optimization
  4. Conferences — from attending to speaking
  5. Building a global English-language network
  6. Leveraging Korean communities
  7. Personal branding ethics

Season 3 Episode 12. If last episode was about "learning," this one is about "connecting that learning with people to turn it into opportunity."

Chapter 1: The Science of Networking

1.1 Granovetter's Weak Ties

Strong Ties:

Weak Ties:

Research findings: Among people who switched jobs:

The key insight: "Someone's sibling's friend" is who brings you the opportunity.

1.2 Dunbar's Number

Robin Dunbar (primatologist):

5,000 LinkedIn connections? Unrealistic. Real meaningful relationships cap out under 500.

1.3 Reciprocity

Robert Cialdini:

"Humans have a strong instinct to repay what they've received."

Give first:

→ Receive later.

1.4 Serendipity

Naval Ravikant, founder of AngelList:

"Luck isn't something you can calculate — it's a surface area you can expand."

Networking equals expanding your serendipity surface area. Meet more people, write more, share more — and the probability of opportunity rises.

Chapter 2: Strategies for the Introverted Developer

2.1 "Introverted does not mean unsociable"

Introverts can network excellently. The method just differs.

2.2 Introvert-friendly approaches

1) 1:1 conversations:

2) Asynchronous:

3) Small groups:

4) Topic-centered:

2.3 Extroverted tactics to skip

Energy management: build in recovery time after any social event.

2.4 Introvert role models

2.5 One person at a time

Weekly goal: one meaningful conversation per week.

1 year = 50 people. 10 years = 500. That's Dunbar's ceiling.

Content types:

  1. Share your own blog posts
  2. Industry news + your take
  3. Career lessons
  4. OSS project updates

Frequency: 1–2 times a week. Too often = spam.

Timing: Tuesday–Thursday mornings (LinkedIn algorithm).

3.4 Connection strategy

Cold connects (first-time contacts):

Example:

"Hi — your post 'A Rust Sharding Story' struck a chord with me. I'm also into Rust and distributed systems, so I'd love to connect."

10.2 Grifter vs Educator

Twitter/LinkedIn is full of the former. Be the latter.

10.3 What to share publicly

OK to share:

Chapter 12: 12-Item Networking/Branding Checklist

Chapter 13: 10 Networking Anti-Patterns

1) Ask without giving

Always asking, never giving back. Give first.

2) Collector mentality

Chasing 5,000 LinkedIn connections. Meaningless. Quality > Quantity.

3) Transactional

Only calculating "can this person help me?" No authenticity. Care about the person.

4) Over-sharing personal drama

Divorce stories on LinkedIn. Destroys your professional image. Keep the line.

5) Humble brag

"Got lucky with a Google offer today ^^" backfires. Be direct, or stay silent.

6) Going solo at a meetup

Standing in a corner on your phone. You meet nobody. Try saying hi to one person.

7) Not following up

Getting a card and ghosting. Connection lost. LinkedIn within 72 hours.

8) Leaking company secrets

Revenue, strategy, internal politics. Legal trouble. Be careful.

9) Endless selling

Every post is your product/service. Followers leave. 80/20 rule (80 content, 20 promo).

10) Burnout networking

Three meetups a day. Exhaustion is imminent. Sustainable pace.

Closing — Networking Is Planting Seeds

Principle 1: The relationship is the goal

Act with authenticity even without direct benefit. Trust compounds.

Principle 2: Giving comes before receiving

Reciprocity is automatic. Give first, it comes back.

Principle 3: Writing is the foundation

Even introverts can have influence through writing. Pick one: blog, LinkedIn, or Twitter.

Principle 4: Maintain weak ties

10 strong ties < 100 weak ones. Quarterly check-ins.

Principle 5: Long-term view

Don't expect results in 6 months. It compounds over 2–5 years.

Principle 6: Read the originals
