Of course, if you do have long-time plans for your personal #knowledgemanagement, you should not use proprietary tools like #Obsidian, #OneNote, #Evernote and alike.
You also should think of switching to a much better (learnability, portability/compatibility, typobility, logic, featureset) markup syntax like #orgdown which is used in #Emacs #Orgmode (among other tools).
But if you start with Org-mode, you need to know the right way of doing it, as so many web pages recommend. Here's my take:

A specific blog post about the #lockin effects of Obsidian and Co (despite using some tool-specific flavor of MD) is in the making. (Please don't start a religious discussion here.)
