Always worked before by just importing URL. Now Twitter claims it is some kind of 'temporary' problem,' but I don't think so. I think they want you to actually sign up. I don't want to. No.
I have 2 feeds that work fine now. (Blago was amusing until he got convicted, not a tweet since then.) I am trying to sign up for a third and it won't work, just an exclamation point, but all the third party hacks and solutions I find only give you the links the Twitterer posts, but this Twitterer I want to follow is just chatty and interesting, no links.
