From the outside it looks like they're at a virtual feature freeze and stand-still meanwhile all other Tech giants are firing on all cylinders with a continuous stream of new features and products.
Meanwhile Twitter struggles at implementing the most requested feature for many years - to edit Tweets. They're also in a prime position to benefit from Live video which they still can't capitalize on, there's no discovery and you can't even subscribe or get any notifications to the shows you're interested in, instead all you see is a tiny animated gif in the corner that's easily ignored as an Ad to show you what's playing.
I don't see how Twitter can continue as an independent company, the best thing that can happen to them is to get acquired and get some new blood in charge of product development, unfortunately there's so many trolls and hate speech on Twitter that no-one wants to touch them - another area they continue to flounder on.
