There you go! That's a good start, believe it or not the initial step is hardest, from here on out all you have to do is consistently share and not care about the outcome. First time of hearing of nicheless, looks cool! One thing I forgot to add is you should have one main platform (website) that can serve as the central link to all your notes. Hell even a public notion page with a list of links and titles of your writing would work. This should be an mandatory practice so that you(or your writing) can be found easily. Idk if you've heard of POSSE[0], its a great practice. Anyway don't worry about half-baked ideas, what you consider half-baked might be baked and ready to serve to someone else. With your goal of connecting I think you can and should disregard that perspective and just send it. I'd recommend using your existing channels (HN, twitter, LinkedIn, instagram, facebook, whatever social media site your on) and share it from there. It's really that simple! Someone is probably reading your post now as I type this. :)
