Looking at Boost Note

What do you think about Boost Note, digital notebook software?

They offer commercial service/hosting, but both versions of the product (“old” one and Next) are open-source under GPL.

An attractive part is the possibility of collaboration (what they call “Boost Note for Teams”).

My only relation to that piece of software is I tried using it.

I’ve never heard of this until now, but it looks interesting. I’ve been using Joplin on my laptop and smartphone for over a year, but might give this a shot.
