I've always wondered this. Google Plus has never really been popular with anyone with people tending to prefer Facebook and Twitter whilst professionals tend to favour LinkedIn. Considering that Google is the largest search engine out there and favoured by most computer users, why did their social network not work out? I mean, I'm sure there are several people out there that still use Google Plus but compared to the user bases of Facebook and Google Plus, it is tiny. Did they not market the social network properly? Or is it just that new entrants to the social network market cannot do well?
