I hear you. I just think that people (particularly if those people are also developers) would appreciate it if they actually heard from the IE developers a bit more. It doesn't have to be to degree where it's interfering with your actual job. You guys should stay in control of how much you interact etc. For me I would find it encouraging to know that the IE developers are just around in places like HN and are listening. I'd know that if they say something occasionally. How much you interact or how much feedback you gather would not really be the relevant issue to me.
Just a thought anyways. :)
