CHIRP is read widely by those involved in professional aviation matters and is being copied in various other states. Whether or not its contents are acted upon by the relevant authorities is for those who have contributed to it, to determine. It is not a substitute for the MOR facility, but it is (in my view) a valuable insight into the concerns of those involved in any form of air safety - pilots, engineers, cabin crew, ATC etc.. The only alternative would be a 'whinge' in PPRuNe, which allows the non-involved to state their more-often-than-not irrelevant comments. At least the concerns of a CHIRP poster are commented on by 'an authority' (whether to your satisfaction or not).
Keep CHIRP going, it is at least an addition to improving air safety. If you feel it is not, then you have the democratic right to file it in the appropriate place!
