I find that people are hesitant to reach out to a stranger. I suppose that's natural. However, it's also unfortunate. I figure that by explicitly stating the good reasons to reach out to me, people will be less hesitant.
Good reasons to contact me:
If you're looking for a freelance web developer.
Advice regarding learning to code, or coding bootcamps - I've actually talked to about 50 or so people who've reached out to me about this. It was enough that I ended up writing an article outlining everything I have to say. I've learned to code via a mix of self-study, a coding bootcamp (Fullstack Academy), a few college classes, and on-the-job experience. I know a bunch of people who've gone through coding bootcamps.
Critique of any of my writing - I very much value this. Eg. for the longer educational articles, I always have my friends read them and then I fix the parts that they find confusing. I think this iterative process of improvement is very effective.
To talk about startup ideas - I love talking about startups.
