Not in any useful way that makes Twitter better or different than other sources of news.
Only if it's directly linked to you. Can't go scrolling on someone's profile without getting blocked by a pop-up. Also can't click a post and see replies.
Edit: also can't read a thread because each new post is considered a "reply", so blocked too.
