Wow! I so agree with the methods here! It just makes so much sense.. 20-30 years ago, when people commute (on bus or train), most of the people were reading. Then people started turning to music, and now most people are using smartphones whenever they are commuting, "free" or waiting for somebody. Because of the capability of smartphone, people can listen to music, play games, read E-Book, look for subjects on the net, and so much more.
With apps related on Buddhism, it will definitely give another venue for the people who are already using smartphone to learn about Buddhism. In my opinion, any form of apps would be good, be it game, E-Book, music, or "do-it-yourself-guide", etc. I wish there are more Buddhism apps for this era.
Also, I also fully agree that for lay people who wants to do serious practice, social media can be a distraction
therefore it should be kept out of reach
Of course, this restriction should not be applied to enlightened masters...
