Everyone loves Discord, I personally can't stand it LOL Way too much going on. I like simplicity.
So Telegram is my go to these days. Crazy simple and easy to use and navigate.
Steem Chat looks simple and easy to use which I'm . huge fan of but yeah dude, I haven't used it at all.
Wonder if it'll be a good plan to even promote it in posts to meet and greet their subscribers / followers....Might have to dive in :)
I like Telegram too. Until we have an integrated chat option for Steemit, we'll have to look for outside applications. The good thing about steem.chat is that it's widely known among the Steemit community so most people are on there.
