Pinterest announced the change with a post on their blog yesterday afternoon. Some people are speculating that the change is something Pinterest have wanted to do for a long while, but were holding off on until they felt confident their systems could manage a big influx of new users. Pinterest’s $100 million investment received in May has likely helped them improve their infrastructure.
According to the best data we’ve seen, Pinterest’s growth has been fairly steady over the last few months; down from the explosive growth they experienced previously, but still impressive for a social network of their already huge size. It will be interesting to see if opening up registration will accelerate things.
