That's why engineers are usually bad marketers (And I'm including myself there) and their technically sophisticated side project goes nowhere because they don't know where their potential clients hang out or they think doing marketing is "cringe".
If you are the best consultant but you don't tell anyone about it, you'll not have many clients. In this case it's not about what you think is the best and most pure platform, but where your potential customers are hanging out.
What's the percentage of people that will read a post embedded in the site vs clicking a link to another site?
Sure, I think it strange that these posters are posting directly into a site rather than writing locally and then copy/paste into the site so that the data on the site is no longer the only copy. But YOLO is real I guess
LinkedIn content is trash to be honest. If I were to put effort into a good post I would ever write it there, no matter how many eyeballs could I attract. The post could be good, but because I have been fed trash on LinkedIn for such a long time, I wouldn't spend a second trying to figure out if what someone wrote is worth reading.
At least for me HN provides me with high quality posts, hence me coming back here for new sources of information. Not saying that all posts on HN are top quality but most of the time the situation is exactly the opposite to LinkedIn. So there's a lot of value to build up your own thing and put work on it.
Do you realize that you are giving content for free to an already enshittified and closed platform?
Open a blog where everyone can read freely without to have an account in one of the worst platforms out there.
Or is it to be popular that you post there?
