The order is by last post time and then by topic ID for tie breaking; this ordering is consistent between different tags, which gets important later. If you iterate through one of these sets you'll get all the topics tagged with that tag, most recently updated to least recently updated.

Tags also define and implement a very simple cursor interface. This interface is basically three functions; "advance the cursor by one topic", "advance the iterator until it's pointing to or past this topic (passing in a reference topic)", and "give me the currently pointed-to topic". When you are talking to the service, you can say "skip 50 topics and then give me 50 topics", and it will advance the cursor 50 times and throw away the result, and then advance the cursor 50 more times while returning each result. Pretty straightforward.

The cursor interface is also implemen
