The only straight up “we’ll let you take up a bit more bandwidth since you’re paying us” feature addition included with Twitter Blue is its elongation of the time limit for posted videos from two to ten minutes. One of very few observations about Twitter Blue I could find from “regular” Twitter Users comes from r/Twitter (which is uh…. a mess:)
the only reason i got it is because it allows 10 minutes of videos you can post and since I make content I no longer have to be restrained to the 2:20 video time on the "regular" Twitter. -u/jdb825
I personally feel this post wholeheartedly - especially since I’ve basically committed to single-take video content, personally, yet have been regularly sharing screencaps on my account. An anecdote I have not seen mentioned: for videos uploaded directly to Twitter’s “Media Studio” (a feature to which I have access because of my peak Periscope fame, years ago,) the two-minute limit still applies. Yet another beautifully absurd product oversight.
From the screenshot embedded above, it’s quite obvious that I no longer use Twitter’s Direct Messages, but there was a time, many years ago, when I would have personally appreciated “Pinned Conversations” very much.
