Some good news about #Mastodon, there has been a very significant bit of code added which will automatically fetch all the replies in a thread. This means everyone will be able to see a thread's whole conversation no matter which server they are on!
The code has just been "merged" which means it should become available in the next update to Mastodon, hopefully within the next few months.

p.s. More info from one of Mastodon's core developers @renchap :
Fetch All Replies will be in the next experimental version of Mastodon (aka the "nightly" version). It will be disabled by default, but will be tested to see how it behaves on a small number of real servers. Once the developers are confident it works okay, they will release it fully to everyone.
Server admins are free to use nightly versions at their own risk, so you may see this on some servers before the "official" release.
