I prefer:

/dev/null
Why? On fast machines, returning results every four or five hours, there is
significant time lost waiting two hours for the next run. Running it twice
per hour means that (on average) my box waits 15-20 minutes idle before
starting the next run. The setiathome process is intelligent enough not to
start a second copy, so running it this way does nothing bad on my system.
And, for courtesy's sake, I avoid contacting *any* server on the hour
(12:00, 1:00, etc.) since too many people do that and the servers get
bombarded at those times. That's why I use times like 17, 42, 51, and so
on... just to distribute the traffic somewhat.
Cheers,
