It depends! In many applications it's the change of state that's most
important. The "lie" is a pull for a bank balance once every hour that
misses two transactions which put the balance deep into the red 
incurring charges and then immediately back into the black again. 

FWIW dealing room screens often colour code to differentiate rising,
falling and /stale/ prices.

The lie is that 'pull' scales well. As an industry we've built big-iron
and caches around 'pull' to make them work and yet most small sites 
still succumb to being slash-dotted. Meanwhile spammers push to wide
audience using the minimal of kit.
