Ask HN: Do you use LinkedIn and are active on it?

I am a Senior Software Engineer and in my career so far I have been fine without using LinkedIn when applying for a job.

There are some downsides to not being on the platform though:

- Lack of alternative networking options at conferences. Keeping in touch with cool presenters or people you meet (email is ok, but requires pro-active messaging).

- Perhaps missing more lucrative job offers?

- FOMO

However the negatives I see are:

- Shallow and egotistical content being posted by "high flyers" etc.

- Cold messaging or soliciting / spam

- Data privacy concerns (as with any social media platform)

Interested to know what people think as a whole of LinkedIn.
