At the bottom of a thread why does it show Anonymous Users? What does it mean by Anonymous users, cause members are shown and guests but who are the anonymous users?

whoops where it says "topic" on the title I meant to write "thread"

It is also quite useful for surfing on the job.

What kind of place that would care about it and not have screen looking/grabbing software I do not know but I guess there are scenarios (especially with the rise of very portable internet capable devices).

Many news sites (while we have news we are still mainly a forum) have similar anonymous posting/browsing options for similar reasons.
