What do you think about DEV?
I don't use it personally. But I have heard good things about it. There is definitely overlap and our target audience is the same. This means there is going to be more innovation in this field and developers are going to benefit from it.
it's open sourced
Even we have similar plans. As I mentioned in my other answers, OS takes transparency and community adoption to a different level altogether. We are discussing things internally and will probably have some concrete ideas about OS plans very soon.
It's always good to have alternatives. We have varieties of options in other fields. Why not have that option when it comes to dev communities? At Hashnode, we don't consider them to be our competitor. We have our own vision, plans and goals - So, we'll grow in our own direction. 😀
