From what I see, first 3 hints -- Naked/hidden Singles, Locked candidates, Naked/hidden pairs, triples, quads, when applied iteratively most all puzzles seem possible to solve. There seem no need (at least for most part) for more complex hints such as sword-fish, etc.

Is there a statistics available on the hints usage scores, for solved puzzles ? I'd think such statistics would show how likely a hint to be 'successful' -- useful info.

Since Naked/Hidden Singles hint seem always the last iterative step in arriving ('Make') at the assignment of number to a cell, obviously would have the highest score. But, others that 'Eliminate' candidates would have varying scores. A natural ranking score sets up an order of hints for resulting in a successful solution. I think this would be very helpful.

This ranking could further rank puzzles themselves within Easy, Difficult, etc. categories.

Is there way to make a MySpace profile look like a Wikipedia Article? I want to see if I can make my profile look like a wikipedia article and type stuff on it so it looks like an article, just for kicks.

Looking to share heuristics for seeing and marking chains and alternating chains using pencil rubber - how to prune the candidate tree, how to identify possible candidates and eliminate impossibles - practical techniques

eg how to easily identify 3-candidate cells with intersecting tuples; how to eliminate tuples quickly; how to eliminate digits quickly - am I on topic in here?
