A few weeks have passed since the launch of Google+, and it has exceeded Google’s own expectations; there is talk of 30 million users before the end of the month. These figures are surprising and, when analyzed without considering the current context, are very impressive and favorable, but compared to the social media giant Facebook, they are negligible. Currently, Facebook has 550 million users worldwide, and although it is starting to show stagnation, or even user loss, in some countries (USA and UK, for example), it still has the potential to continue growing.
Facebook has the most important thing in its favor: the users, whom it keeps semi-held hostage in its network, making it difficult for them to leave for other networks. In this regard, the case of the Chrome browser extension, Facebook Friend Exporter, is noteworthy. It allowed you to export your Facebook friends list to CSV or Google Contacts (which makes moving to Google+ much easier). I was able to use it without issues, but for a few days now, it has stopped working because, as its developer indicates, Facebook is putting up every possible obstacle to its operation. I won’t go into much detail about how Google+ works, as many blog posts, news articles, etc., have already been written about it, but I would like to share my opinion on what Google+ is currently missing to keep moving forward.
API
There is no API available yet, although there is already a pre-registration to request notification as soon as it becomes available. The API is a very important piece that will allow, among other things, access to our G+ network from applications like Tweetdeck, Hootsuite, Echofon, twicca, etc.
Business profiles or pages
On Facebook, a marketing ecosystem has been generated around business pages, which are also a way to stay in touch with companies of interest. These shouldn’t be missing from G+ either.
Games
We geeks probably won’t agree with this—we don’t need them, and they are often a source of spam—but for the average user, they are important and can be an attraction that invites them to make the jump to this network. Google’s purchase of several online gaming companies a few months ago and the discovery of strings related to game invitations in the G+ JS code suggest that this will be a reality very soon.
