It's impossible to follow a twitter conversation if you don't understand how twitter works. It's a huge barrier to entry for new users and I don't think they'll start growing again until they fix this problem
Would you please suggest a good overview of this? I've been on Twitter for years and sometimes use 3rd party clients, and my UX still sucks. I can follow Twitter conversations but find it virtually impossible to initiate one. I limit the time I spend using it because it makes me feel autistic, whereas I find other social media liberating.
