Google’s decision of changing its 3 month old social network Google+ from “invitation-only” to “open access” available to everyone proves to be right, as it emerged as the third largest site in the Social Network and Forums category. This happened on the last Wednesday, a day after the site went from “invitation-only” to “open access” available to everyone, as per a report by Experian Hitwise.
Opening access created a massive spike in market share of visits for the site, with a 1269% growth from the week ending September 17th to the week of September 24th. The site also received nearly 15 million total US visits last week.
The evolution of Google+’s audience composition from its launch in early July to last week illustrates how quickly the cycle from “Innovator” and “Early Adopter” phase, to the “Early Majority” and “Late Majority” can occur.
