Boost still looked nice, but the posting UI was terrible for me. I couldn't figure out how to do half the things I wanted to do, and since I became a regular poster using a ton of media and formatting, it was just a no-go.
The dev has done a lot to help with my specific use cases, and I haven't started since. I gave everything a look around the end of the year to make sure I wasn't missing out on anything, but at this point I don't feel I'm missing a thing from the experience.
I like the apps are all independent in that we can try one or all and hop between them at will without losing anything.
