But this is not a problem of the platform, but of how users are using the platform. I rarely have conversations on twitter (i.e. most are just a couple of replies long at most) but I occasionally have a 20+ post. If you hit proper reply, it works. If you don't, it doesn't (or does really badly), but this is a user fault, not a platform fault.
If users have difficulty properly using the platform, the platform is at fault. An arbitrarily naive user should never have to fight the platform to do what he wants.
Also consider when there's say four people tagged in a conversation, and then someone needs the extra characters to make their point and they remove one of the names, then that person loses the context too.
Also, conversations look different when you're looking at them from one of your lists, or if the people you are following are different than the people I follow.
So many clunky issues that you need to be on top of for it to make sense, and this is what's lost on the general person.
