I tend to use it as a news feed rather than socialising. I find the conversation less "Volatile" and as such it is a "nice" place to be.
That said, if I want to speak to people like I would in the pub amongst my friends, I use FB. There's only really my friends that are interested in tech that use G+ The rest of my friends are very quick to dismiss anything that requires a bit of thought lol
Deep down, I think they were that hell bent on slating it, now that they know that it is here to stay, they are embarrassed to get involved
Like they did when I first pulled my Galaxy note out......
These are the guys with Android phones who swear blind that they don't have a google account
So how did you register your phone and what's the point?
I think over here in the UK, it just requires a bit more positive publicity and correct marketing (It's not a direct competitor to Facebook but more an enhancement to be used in conjunction) and it would take off. If it were bundled with every Android handset, people would find it and use it out of boredom
