Yes I use pocket and am fairly satisfied.
Why do I use it? Well, I have been using it for about 6 years, was the first thing to work fine in my mobile, don't want to install another extension in ff, hate bookmark handling by ff (at least in mobile), and want to push myself in reading.
Although I nowadays see too much american articles in pocket to be relevant for me.
Correct. They have the history of "the best use of desktop space" from unity DE. Although I will not forgive canonical for dropping unity, the gnome they have is close.
