That btw was one of the #GooglePlus features that really pissed me off and made me use it a lot less: the +1'ed by a friend promoted content, which more often than not was irrelevant to my interests, as it often included family photos of people I only followed for a specific interest. Along with the What's Hot posts, which increasingly became mostly about 'celebrity' nonsense, they just polluted my stream with noise.
The influx of mainstream users also made #GPlus go quickly downhill.
