Other Twitter apps and twitter.com show you pictures of users whom others have retweeted inline. Thus, you are seeing random people in your timeline simply because they got retweeted by someone you follow.

It’s a conscious design decision in Crème not to do that. We only show the people you follow. If they retweeted someone, you see a simple “RT: something something” notice. If you then tap on it, you see the original poster.

Similar logic is reflected in a setting in new Twitter that you may or may not have noticed.

We decided that showing random people in your timeline is a bit annoying even if they have some cute “retweeted” icon. So Crème’s timelines will remain clean, but you can drill down and explore new people by tapping on individual tweets.
