It was like that in the earlier days. Every update kept reducing the amount of visible content, and severe reductions in density. Here is a screenshot of my screen - http://i.imgur.com/fM2WIVf.png (1920x1200) - almost two million pixels. There are a total of 7 (yes seven) sentences of article and 5 sentences of comments. I have to click and/or scroll to see anything more. (This is their densest layout - the single column version has a total of 4 sentences.)
With Reader they had a community of people who read a lot, and an interface design that worked well for doing that. They took that away. By not having access via an open standard like RSS for G+ streams, they don't even allow alternative interfaces that can address their problems.
I can only conclude that the people who persevere with G+ do so despite it, not because of it. They must also be very patient and do a heck of a lot of scrolling.
