Feedback on products is atrocious -Google Now on my iPhone shows me a route home that would send me the wrong way up a freeway, and I don't know where to report it. Years ago, I ran into a serious issue with Google Desktop, and the bug was poorly documented.
Their maps data in Johannesburg has some annoying data issues, and is rewriting the geography of the city, because it is relied on by third party sites. They do respond to some Maps reports, and other problems can be fixed in Map Maker, but some are too big.
The common thread in these problems is that Google has very poor feedback mechanisms - a problem that has existed for years. Given their success in organising data, you'd think there would be a way for them to handle feedback efficiently, and in a standardised way across products. But feedback doesn't seem to be a priority. A few months ago, HN became an unofficial support board, with various tales of woe posted here, and then fixed by Googlers
If they get their feedback and bug reporting right, I'd be willing to cut them some slack: as a company, they aren't particularly abusive. Wanting to clean up YouTube comments is commendable and overdue, and their search engine remains very useful. It's easy enough to lock down a Google+ profile if you want, and to tweak Gmail to be less annoying.
