I totally agree with you: leaving stakes in and yellowing leaves attached is unsightly (and certainly makes for a poor "sales pitch").
But sometimes I feel caught on the horns of a dillema. I think it's important that people who are relatively new to growing realize that leaf loss is part of orchids, and nothing to freak out about when it happens. When people question that, I always refer them to the award-winning plants in the AOS ORCHIDS magazine, many of which, if you look past the gorgeous blooms, have a brown leaf or two at their bases.
As far as the stakes are concerned, you're right: nothing could look more unnatural. Plants with two spikes that are rigidly staked look they're wearing some kind of TV antenna. It's unfortunate, but since many of the plants we have are epiphytes which are accustomed to hanging down from the trees, without staking, their blooms become so heavy that the weight of them will break their own spikes. So we have to ship them (and photograph them) staked to avoid breakage and damage.
Where I can though, for the pics I post in this section, I'll remove the stakes, especially for semi-terrestrial things like slippers....
(I *am* going for the Glamshot, after all!!)
