I’m in like 10 different pools, my view on various pool managers:
* PicksPal Bracket 2007 – NCAA Tournament – March Madness — easy to enter, a lot of ad content but not annoyingly so. Entire bracket on one page which is nice.
* Sportsline. I LOVE LOVE LOVE the fact that they show you consensus pick info dynamically as you pick teams — this is freaking awesome. OK the math is sometimes bizarrely wrong but still. My favorite.
* Yahoo. A fine choice. Not fancy but works well.
* ESPN. The worst. Abusive ad content — in tooltips popups, in between regions as you fill in your bracket. I won’t bother to fill in anymore at this site and i would certainly never host one here.
