Decimal time is cute (albeit not very novel) and makes imho a lot of sense. I'm secretly hoping that maybe on Mars we could end up using millisols for timekeeping.
On the other hand dividing a year into 1000 does seem bit more of a novelty, and not very practical. I suppose it is bit of a reminder that the year is passing, in the sense "oh dear, this year is already 87% done"
I also don't think that you can orientate on dates in a decimal manner.
With dates it's easier to orientate, but you don't get the exact feeling on progress.
So yes, same as you, when I'm seeing it from time to time I get motivated to do more in the time remaining for the year :)
Open for feedback!
