Last year, we launched YouTube Go in India, a brand new app built from the ground up to unlock the power of YouTube for the next generation of users. Since then, we've also launched YouTube Go in 14 additional countries, including Indonesia, Nigeria and Thailand, and we've seen firsthand the impact that bringing more people into the world of video can have.
One word of warning: Many dating apps require Facebook integration to work, meaning you won't be able to use them if you delete your account. You can still create a Tinder account without Facebook, but you will loose all your current matches and conversations. Hinge and Bumble require you to have a Facebook account to sign up, though the latter company says it's working on dropping that requirement.
A simple chat (slack style) it's enough. Just having the possibility to send messages either single user or team (#channel). But please don't forgive to give an useful appeal to mobile app (worst error of competitors is, have a good app but totally no mobile friendly!) i would expect to have a similar whatsapp or slack app for messaging within the slack mobile app!
