Social Media Networking

As a very simple summary, you need to do the following:
Be active on social media.
Search out and communicate with people in the sector that you are interested in.
Don't look at everything as a transaction; look to develop relationships.
Don't focus on one person, be flexible and look for groups of people and don't obsess about individuals.
Favour people you have a natural rapport with over someone more important who turns you off personally.
Don't forget to be a nice person. Relationships should be a win-win for everyone if done correctly.
Both consume and produce content; schedule your consumption and set up your notifications so social media doesn't take over your whole life.
Don't waste time producing large-scale content like a blog or a podcast unless you have other valid reasons to do so (like you have a particular interest or to build a business).

think if your aim is to find a job then I think any content you produce should show your knowledge and interest in the kind of job you are looking for.

generally the principles are to show interest, attention and care.

The most important kind of interaction is of course commenting on people's posts, either as tweet replies, or as comments on Facebook and LinkedIn.

But clearly "be social" and "be human" is too general advice.
