I know for lot's of folks an outage needs to last awhile to make it worthwhile, or at least line up well with the other sites in the generally region but what i'm talking about is the 'fun' factor..
used to be we'd have the long outages and everyone would get to know each other, have time for a few good parties (or sometimes just one party that went the duration).. you'd have outage tee shirts that were tied to the key events, etc...
but these days we hardly get to know each other, there's no time for much partying because before we can agree on where to have it, we're all packing up for the next outage...
on the other hand, for me the best two days of an outage were always the first and the last... so a shorter outage never bothered me much...
