Why do so many people in Stack Overflow try to answer the answer by adding a comment to the question instead of adding an answer which, I suppose, is the correct way? Are they just trying to get visibility?
Yes, but that test only applies to official apps... Do we have usage data on those? Especially taking into account very good apps already existed and most users probably couldn't be arsed to switch to the official one.
Those official apps have lots of downloads, but don't be fooled: I bet most people downloaded them because of the free three months of reddit gold you got when you logged into them.
