So, I have spent a while using Google Plus. Along side my uses of Facebook and Twitter.
Ultimately, I didn't like it.
There wasn't anything in particular it did wrong. But it didn't do enough to keep me engaged either.
I have to admit all I used it for was to crosspost stuff from Facebook and Twitter onto it instead. Some of the technology podcasts I listen to liked to talk about who it was somehow better or at least where more of their types of people hang out on the internet.
