I get pleasing results with this formula:

sub tension { my ($hi, $lo) = @_; $lo or return 0; 2 * log($lo)/log($hi + .1); }
where $hi is the higher number of votes (whichever direction) and $lo is the number of votes in the other direction. Any result above 1 represents an interesting amount of tension, IMO. Here's a table of results:
Hi #Lo #Tension
3 31.9420
8 31.0504
8 81.9881
20 30.7322
20 81.3860
20201.9967
50 30.5614
50 81.0626
50201.5308
50501.9990
90 30.4882
90 80.9240
90201.3312
90501.7383
90901.9995

    That looks pretty good, except it seems to lose the magnitude of the tension. 3 vs 3, 8 vs 8, 50 vs 50 all have similar results.

    (of course that's probably just me visually eyeballing sig figs along a log curve...)

    Cheers,
    Matt

      You're right. My notion was only to distinguish interesting from non-interesting. You regain the magnitude if you drop a log: I'd call < 1.3 low tension, 1.3-2 moderate, >2 strong.
