The write-up at http://docs.mongodb.org/manual/core/tag-aware-sharding/ raises the issue of chunks with data that belongs on two shards being put on the shard whose tag is the closest match. While this is technically correct, I believe we should point out that pre-splitting and manual migrations can keep this from happening. Otherwise tag-ware sharding is really of limited value.
