I think there is wear leveling that's pretty similar to SSDs. If you use a filesystem without journaling, it shouldn't be an issue. If the wear leveling is good enough, it could be that even with journaling, there's no problem. One could of course use jffs2 or another flash fs that has wear leveling in it if it proves to be a problem.
