It had been expected, Tweetdeck is now no longer available to me to follow Twitter topics and lists. Tweetdeck is only available to paying Twitter accounts. Earlier today it still worked for me as a non-paying account, now no longer. It went web-only a year ago before Twitter’s transition of ownership. Last month it became clear Tweetdeck would be limited to paying accounts. With Tweetdeck gone the last remaining shred of utility of Twitter for me dissolved.
