Google doesn't really seem to understand their own product. Most people love(d) it as an independent social network because its features are way better than those of Facebook and others, but Google keeps messing it up by nerfing or removing popular features, adding useless ones, integrating it with the low-quality comments on Youtube, not showing everything you want to see, showing things you don't want to see (the hated "+1 sharing"), etc.
It could have been fantastic, but Google seems determined to kill it. Lately I've seen very enthusiastic early fans leave Google+ and just submit to the horror that is Facebook, because at least that's predictable.
