No, it's not "obviously ok" for conversations if "millions of people use it that way". What kind of strange thought process leads to that conclusion?
It's only "obviously ok" if (a AND b), where:
(a) "millions of people use it that way"
(b) it's productive and beneficial when used that way.
The (a) is only enough to show that Twitter serves a need people have for certain coversational structure (short messages). Doesn't prove that it's the best tool imaginable tool for the purpose or thats it's the pinnacle where evolution in such networks stops.
Actually, this very thread started with a FA saying that it's not (b).
People don't generally voluntarily use a service unless it is beneficial to them in some way. It's not like millions of people are being forced to use Twitter for conversations.
Edit to add: also, I didn't try to "prove that it's the best tool imaginable tool for the purpose or thats it's the pinnacle where evolution in such networks stops." I just said it's ok.
