This is the “Dropbox is just rsync” comment
While that's a bit of a joke that gets tossed around occasionally, i don't think that this makes it any less worthy of a discussion. Sure, Dropbox might have bunches of complexity, but if you have a simpler alternative that works for you, why not consider that in earnest?
Thus, i think the comment stands and if nothing else, will probably lead to some folks sharing more information about their setups and what works for them, like i did in another comment: https://news.ycombinator.com/item?id=29932945
The only caveat I will give is, is that you can do so much with it with the stock options and its graph and throw in the plugins you can get within the app, you can easily spend so much time trying to perfect everything. I got burnt out with notion really fast since most of the community at least on reddit gravitates to showing off what your landing page looks like.
