It would be a somewhat safer place for life than within a galaxy proper - far less chance of a close approach by another star kicking your planet out of its solar system, less chance of taking a sterilising hit by a close by gamma ray burst. Those living on such a planet might even reasonably conclude that advanced life on a planet within a galaxy, like our own, was very unlikely.
