I agree that the blog page should be limited to steemit....

Perhaps they could make tabs for the commonly used apps like d.tube, zappl, etc. with a catchall for everything else. Or even better, allow the users to alter their tabs. If you want zappl but dont use dtube, you can switch it out so all your zappl go into that tab and use the other for something else.

Overall, I agree that all of these apps are going to help the steem blockchain. It appears the entire social media spectrum is being covered. Over time, as the bugs are worked out, these apps could be threats to the instagram and twitters of the world.
