Twitter ^[1] has an option to view users profiles, however, in those you cannot see a user’s timeline and who is replying to them. However, a service ^[2] called cTwittLike ^[3] will allow you to see Twitter like someone else views it.

For example, if I wanted to see the timeline as our update robot on twitter @techiebuzzer ^[4] does, I just have to enter the username techiebuzzer and wait a few seconds to view twitter like I would do after logging in as @techiebuzzer.

If you want to take the shortcut route, just load up the URL http://www.ctwittlike.net/username, to view the timeline like another user would, just replace the username with the name of the user you want to view the Twitter timeline as.
