The Facebook Home has received mixed reactions among those who have tried the "beta" application/launcher. While many approved of its smooth and convenient way of keeping tabs, others complained about difficulties accessing other applications and that they do not really have use for the launcher.
The Google Play Store has recorded at least 500,000 downloads almost a week since it was launched. This number seems quite disappointing, considering that FB users amount to over a billion individuals, showing how diminutive this number actually is compared to the total FB population. Many consider it grossly underperforming and even compared it to Instagram for Android, a photo social networking site that was downloaded a million times on its first day and has reached 5M downloads in less than a week since it was started.
On the other hand, many people were implying that the Facebook Home launcher was in beta and that the figures should not really concern Facebook officials that much, since only a few devices can actually use it as a launcher. It seems like they're missing the whole point of launching a beta test.
If it creates a significant interest and many people tried and LIKED it, then it will most possibly become a profitable launcher in application stores. However, with these kinds of figures, where testers posted less than stellar ratings, it will not be surprising if Facebook officials will overhaul it or write it off on their lists of applications to pursue in the future.
