Finding a tech geek who can put together a coherent sentence is hard, and there are always manuals to write, tutorials to create and deep blog posts to make -- many of which need the kind of in-depth understanding that only a tech geek can bring.<p>It doesn&#x27;t always need a technical background -- a friend of mine found a job writing drug trial instructions even though she had no background in medicine or biology. But she was pretty exceptional, and very quick on the up-take so she probably absorbed a couple of years of medtech education in the first few months she was there.<p>So yes, you can make a career out of that. Apply for jobs and say &quot;I want a role where I can program 50% of the time and write all your public-facing words the other 50% of your time&quot;. There are many employers who would pay a premium for that unique combination of skills which you have already demonstrated.<p>As for freelance authoring... I&#x27;m writing book #8 now. 
The first 6 are all deeply technical books on backup and managing IT (<a href="http:&#x2F;&#x2F;www.ifost.org.au&#x2F;books&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.ifost.org.au&#x2F;books&#x2F;</a> );  the seventh was a collection of mathematics&#x2F;computing&#x2F;physics poetry ( <a href="http:&#x2F;&#x2F;www.ifost.org.au&#x2F;books&#x2F;outlinks&#x2F;medusa" rel="nofollow">http:&#x2F;&#x2F;www.ifost.org.au&#x2F;books&#x2F;outlinks&#x2F;medusa</a> ).<p>These are rather small niches, but in most of these areas I&#x27;m one of the leading experts in the field -- usually because there&#x27;s no-one else writing anything.<p>Based on what I&#x27;m getting from my work so far, I&#x27;d estimate that I would need to get to 50-100 books written before I could stop relying on other sources of income. I live in an expensive city and have a family, so you might be able to do slightly more easily than me. Also, if I wrote something less niche, I might have a bigger market (but probably face more competition).<p>In other words, I might be able to write full-time in 10-15 years&#x27; time if I keep up the current output. That is something I am aiming to do, but it&#x27;s obviously not a short-term goal.
