Twitter feeds normally look like this: "[Your long name]: [Your update text]." Supply a Twitter username (the short username in your Twitter page URL, i.e., in http://twitter.com/nbr you'd use nbr) and it will give you back a feed with the initial text (i.e., the "[Your long name]:" in the example above) replaced by text of your choosing (enter as "Text for status post title"). That text will be hyperlinked back to the Twitter status permalink. If you want the Twitter favicon instead, enter the word "logo." As an additional feature, it is supposed to make hyperlinks "live," but it only works for the first one, since this is the first time I've ever tried to make something like this and I really have no clue what i'm doing. Have a look at http://nbr.tumblr.com to see it in action.
