This has not been my experience. If you do interesting things then there are plenty of people who are willing to bring attention to it. I've been cold-emailed by journalists wanting to interview me without ever doing anything other than a) make my work publicly accessible and b) collaborate with like-minded people.
Perhaps I'm lucky (probably). Perhaps my work would've gotten more attention if I spent more effort promoting it (probably). The things I do because I find them interesting are not things I feel the need to promote, because I'm not doing them for attention.
If your goal is to grab a lot of attention, you will inexorably have to do things that are not interesting because the only way to achieve broad appeal is to not offend anyone's tastes and the only way to do that is to be bland.
