because both are correct from grammatical standpoint. Yet, they have very different meanings, they are used in different contexts. There are many comments above explaining the difference in great detail. If you don't trust the comments above - ask your several native speakers to comment on those differences.
not to mention that "well-traveled" is an adjective, so if one describes himself in a website profile, (that's where the topicstarter's example came from in the first place), e.g. "I am sensitive, sincere, well-read, ..." then it's smoother to continue the list with an adjective descrbing yet another quality, rather than insert a whole new sentense
