When Google launched its new instant messaging application, Hangouts , there was a tremendous chaos of which are remembered for a long time. There were users who had access to the app (presented as an update of Google Talk) before others, reigned confusion and misinformation ran at home . Soon they began to share files from one place to another, and in general the public was not at all happy.
since many applications have used the same method of staggered launch Hangouts, also known as “rollout”. This distribution is that not all users have access to the app or upgrade at a time, but at first only a few lucky ones can install on their devices. After a while that percentage is enlarged, until finally all users have access to the app. This system is supported by Google, which provides developers with tools for this type of release.
Why launch an application like this? Programmers have their reasons. The main one is that in case there was a bug or something wrong with the app (such as server overload), this could be eliminated or revert to a previous version affecting a minimum number of users . In this way those developers who are unsure of the stability of your app can have this grace period allowing them to turn back.
fact remains that such releases may be a tactic to cause a demand for the product. And that man is curious how rare is interested more than usual, and artificially limit the number of users that can test a product tends to create more interest in the community. Google itself has had success using this type of campaign, limiting the use of services like Google+ or Google Wave to generate interest.
However, this system has its negative points. Not only causes some annoyance to users who have had the misfortune of falling between the last ones who are allowed access, but encourages unsafe practices . For example, to get the package the application apk unreliable sources, which can lead to install viruses and other malware on the system. Also the interest generated is a double-edged sword: may initially improve the downloads, but if it is abused the public just losing interest , as demonstrated by the fact that it ended invitations to Google+ being teased by its uselessness.
