How fast do make your play?

[Barcalounger]

I multi-table so making snap decisions is key. Whether it be fold or poooosh, I usually take almost no time to act unless I happen to be bubbling on a couple other tables.

I know that online reading of other players according to how fast they bet is flawed at best. However, there are opponents out there that are trying to do just that. How much am I giving up by not milking the clock in certain situations? What situations would they be?
