Because platforms (like MySpace) can disappear almost overnight, I would always recommend setting up a blog on a domain that you own and control. Mine is https://markgreville.ie and i have been on the front page of HackerNews a couple of times. I have had lot of people reach out to me over the years, including some very famous tech luminaries (people who’s books i read from cover to cover as i was learning to be a programmer, then architect, then leader). I have also found a lot of great talent through it.
My struggle initially was worrying that i would seem pompous for writing publicly, and that no-one would find any of it interesting. However, most of my friends ignored it, and i found a community on HN that was my tribe instead.
If you are reading this and haven’t blogged before 1. Register a domain now 2. Set up a simple site (Wordpress will do for now, don't over think this bit) 3. Write about something you have done, or something you are passionate about 4. Have a trusted person read it for you and take feedback 5. Edit, publish, and post on HN 6. Start the next post
