I have similar number of hobbies: short term stock trading, golf are two major ones. They occupy my week days. Other hobbies include reading books, listening to music, following Japanese sumo wrestling, gardening, learning new languages, ..., and doing absolutely nothing at times.
I think it depends on the time of the week.
On the weekends you should never have any "tricked up" pin positions. The goal on the weekends is to make pace of play as fast as possible, since that's when the majority of golfers come out to play. To that end you should be placing the pins on the flattest, widest spots of the green to minimize time golfers spend putting on the weekends. It's the same reason that maintenance crews will put the tees about as far forwards as they can go on the weekends, as long as there isn't a tournament going on that day.
On the weekdays you can be more creative and set up the golf course to be more challenging. That being said, you shouldn't go too overboard since it's not the Sunday of the Masters, so I'd say maybe 2 "tricked up" pin positions per side would be the maximum. Regardless of whether they're "tricked up" or not, they should still follow a couple basic rules of thumb:
The hole should be no closer to the edge of the green than the height of one flagstick
A ball should always be able to come to rest next to the hole when rolled from a distance
The hole should generally be at least a few feet from any ridge, to allow good putts to still remain near the hole rather than penalizing someone who putted the ball a foot or two long.
As long as those big three conditions are met, I say put the pin in a couple "tricked up" positions per side to keep things interesting without making the whole course a grind to try and score.
I once got a free Wilson Staff golf shirt and golf hat for buying a dozen Wilson Staff "Smart Core" golf balls! And, at a discount price! I can't imagine what that promo cost them. I long ago lost all the balls, but I still have the shirt and hat!
