TradeHill is running extremely slow. Instant buy and sell is effectively worthless today. That market data page needs to be static. Anyway, people should be using bitcoincharts to monitor the price methinks.
This means they have nothing like mtGox.com/data/ticker.php ...which loads super-fast, correct?
Edit sample w/
old higher prices showing {"ticker":{"high":24.99,"low":16.08,"vol":97956,"buy":22.0004,"sell":22.2488,"last":22.2489}}
