I just did a Glu survey last week and I'm still feeling disgruntled. There was no feedback form and it was written HORRIBLY and unlike most of the surveys I take there wasn't a "write to plony almony with comments or complaints" at the beginning plus as the consent form says, it's a commercial thing for profit.
And this is of and for the diabetes community?! Screw that. I'm not filling out any more glu surveys.
