The notion of delaying proposition of 'solutions' as long as possible seems an excellent technique for group work where stated propositions not only appear prematurely but become entangled with other, perhaps unproductive interpersonal dynamics, and where the energy of the deliberately 'unmade up' group mind can possibly assist the individual to internally change position. The thorny bit for me however, is the individual trying to 'hold that non-thought' - a challenge that is more or less equivalent to stopping, or even slowing the thought process deliberately, which is meditation after all - something we mere mortals haven't found all that easy so far. Indeed, some argue that many of us aren't even aware there is an 'internal dialogue', let alone knowing how to stop it. In other words, it's easy to say don't make up your mind, but not so easy to enact.
I agree with komponisto somewhat, even though I'm a newbie around here. I think the danger of this putatively 'democratically constructed' body of discourse sliding off the precipice into becoming a mutual admiration society or worse are sufficient that there needs to be some discipline applied to dismissive actions. Therefore, some form of reporting on why one has been 'disappeared' might be in order. In the case of being downvoted out of existence, an automatic message stating this could be sent to one's profile (attached to the draft) with minimal effort surely. Where a comment or reply has been specifically removed by an admin, surely it's common courtesy to say so, and maybe even offer a reason and by implication the right of reply where a misunderstanding has occured (yes, it happens!).
