Today was the first time I have heard of scorum. Their coin does seem more stable than Steem. https://coinmarketcap.com/currencies/scorum-coins/
I didn't notice any slowness with Trybe today. I do like the Steemit setup better but for the people obsessed with the Trending page I think Trybe is better. I don't know if Trybe has a feed like Steemit has. My mini Trybe article did get approved but I don't think I have gotten any upvotes or money off of it.
