So the website tries really hard to not give much information.

Given the name I expected some sort of power user desktop app integrated with the system, but after going through the form it actually is a very simple webapp.

There's two buttons to create text/code entries, a per-day view of said entries, and a search bar.

I think that the idea is good, I could certainly use a better tool than my text editor to keep a journal of everything that matters to me, but in its current form I don't see how having to manually post text notes on this webpage would make the task significantly easier.
