I suppose for retrievals this structure has advantages, but unless MySQL has a ++ operator (or better yet, one that adds or subtracts 2 from an int) then it looks to be a pain to add nodes. But I will play with the idea. Maybe after I write the code (I'm saving that for tomorrow) I'll see it differently.
