[maybe-ot] Pdf annotation

Hi,
I need a pdf reader that make be able to put annotation/comment. Many 
sites proposed Okular but in the cons they said:

"Okular is a KDE program, which means GNOME users will have to download 
lots of dependencies to run it, which will take up a good amount of 
space (not to mention it'll look a bit out of pace with their other 
programs)."

So what do you use for that?
