1) How come this one app in particular seems to permeate all the media I consume (even though there is no way to try the app out right now)? In the same week, several podcasts and friends recommended it to me, and now HN. Kudos to whoever organized this launch.

2) I decided this year my personal notes are too long-term and important to me to keep entrusting to every new cloud startup that pops up.

Right now my notes are mostly in markdown files, synced by Dropbox. More developed thoughts that need to link to each-other I do in Trello (I like their UX and how it helps me think).

I'm looking for a system that has these features, but:

- where I will always be in control of the data (open source?)

- syncs & backups reliably

- seamless on mobile
