yes, but not a real time solution.
some people talk to me said that they want their post to appear in the main page exactly on a certain time, e.g. 15:30, and i think it is reasonable in fact.
besides this function, cron function maybe also used in :
1. house keeping, e.g. disable blog without activity in the last 3 months
2. generating site statistics, such as how many posts posted yesterday, how many blogs created etc.
also, for the template cache, i think set to -1 is really good, so maybe try another method to load the calendar?
