OEIS "Top N" lists?

[Leroy Quet]

Or perhaps sequences could be judged upon the integers themselves.

It might be interesting to rank sequences by, say, the sequences with the 
fewest number of terms in common with other sequences (compared among 
terms appearing in the database, of course).

..Or by the most uncommon absolute-differences among terms, the sequences 
whose terms average the highest, the 'most chotic' sequences (ie. least 
able to fit to a low-order polynomial, or some other definition of 'most 
chaotic'), the sequences which contain the most terms of other sequences 
among the terms listed (but in some non-respective order as to avoid 
trivial cases), the sequences which contain the longest runs of 
consecutive integers but which miss the occasional integer (ranked based 
upon some formula involving the lengths of the integer-runs and the 
number of ommitted integers among the consecutive integers), etc etc...

Perhaps rankings with more serious motives can be created, such as those 
which inspire research into connections between sequences, connections 
that would not have been obvious at first to the casual OEIS user without 
the computer-aided analysis.

thanks,
Leroy Quet
