Mental Health

Tech companies don't hire people who know their stuff. Tech companies pay contractors who know their stuff to do the things their trained employees can't. They arent looking for a full cup. They need new meat to exploit while it's still too dumb to realize how hard it's getting shafted and then to dump it before it makes itself irreplaceable.

It also doesn't sound as much like you're looking for engagement as you are employment ("people with money don't pay attention to me"). If money is the end goal, you want to do advertising, not just engagement. If engagement and community are what you truly want, then I'm afraid to tell you those things generally cost money instead of generating it.

Contracting work would be the best case of having your cake and eating it too. Contractors form their own communities wherever they go depending on the trades in question. I think you'll find the network of likeminded individuals you're looking for there. However, be advised that contracting is regulation heavy and would greatly benefit from a few focused law courses before really trying to get yourself into bidding jobs.

Are you actively looking for a job? (Are your posts ONLY for a job, or are you also kind of looking for general engagement/interaction)

Honestly people who post daily with no traction seem more crazy to me than the people who feel defeated after day number 7 and just stop posting. It's totally human to feel bad when talking and nobody stops to listen.

I know some people treat blogging like a journal instead of a showcase. Writing to their future selves instead of a general audience.

In terms of getting traction for employers, posting in small communities with people you are acquainted with seems like the way to go. (@people-other-than-OP, I talk about that more in a different comment)

The trend of video over text would be the main thing you should remind yourself of. They may not read your text, but will watch a ~5 minute video filled with fluff.

It also really matters when and where you're posting them, and if you're sharing them or not.

Social media marketing is an entirely different beast than any other tech field.

You don't have the same skill set outside both operate on computers.

I have my master in Information Technology and had to learn from the beginning once I decided to learn social media marketing and marketing in general.

My best advice for you is to hire a social media marketing manager. You can get them pretty cheap, too. They'll make you be seen guaranteed. You have to spend money to make money after all.

It sounds like you have invested a lot of time and effort and not seen the results you are looking for.

I would suggest you listen to an episode of the Freakonomics podcat. The upside of quitting.
