My LinkedIn network is my biggest audience. I use it to post random thoughts and whatnot, because it's more fun when you know there's an audience. I rarely get any views or likes though.
Get a dog and every day take it on a long walk-and-talk where you tell your dog all your hot takes and random thoughts. Your dog will look forward to this, will look for you on days when you forget or think you are too busy for the walk-and-talk, and as a side benefit, you will get a little exercise, some sunshine, and fresh air.
It can also help clarify your thinking. If you can't convince your dog that technical debt is widely misunderstood, then how will you convince your colleagues?
