Thanks @waybeyondphadthai for discussing some of the greats apps used for steemit. Personally My favorites are discord & esteem. Steemit is not all about writing the good content but it's also about make good relationship with your fellow steemians. You need strong bonding b/w you and your supporter. Beside strong bonding and relation you also need some guidance and I think Discord is helping us in this regard very well.
Esteem is a great app by @good-karma It is easy to use and work like a charm.Yes it gives decent upovte on quality posts.

Even though they take 10% fee, it would still be a good deal for most Steemians

Pardon me for my ignorance. How they take 10% payments. I don't understand. Would you like to elaborated. Thanks for great sharing @waybeyondpadthai
