I voted for "I'd prefer it not be.."
I don't stealth much and I agree that the "cat is out of the bag" / "if you're not an idiot you can probably figure it out". BUT, I think there are valid reasons to keep it discrete and mostly over PM:
1. There are hardcore stealthers out there whose methods are a lot more advanced than the normal stuff we talk about doing (see, e.g., the crazy thread about the dude with the custom wig...). I'd hate to see their techniques discussed in any detail. Also, stuff like the "brand of hat" while maybe out of the bag and all, certainly should be repeated less often than it is.
2. People who record openly and with permission want to keep a clear distinction between the two types of taping. Having lots of open stealth discussion might wrongly give the impression that everyone here condones that activity or that that is all "taping" is about, which it isn't. I personally have no problem with stealthing as long as it's non-commercial and there is at least some valid reason to do it (artists' lame management, venue rule, etc.). But others feel more strongly about it, and I respect that.
