I tinkered with your most recent post a bit, hope you don't mind. If so, just don't poke me with real pointy stick.
Anyway, I think that the square bullets look a bit snazzier than the default circle bullets. What do you (and everyone else) think? I know, it's a pointless thing really but the site is real clean with all of the 90 degree angle, square/rectangle design so the round bullets just look out of place to me.
Tip: If we all decide to go with square bullets you've gotta use the following syntax:
<ul style="list-style-type: square">
...instead of the depreceated: <ul type="square">
