There's a lot of information in this forum and other forums for Google to analyze. I'm sure someone with some authority to discuss future algorithm changes has seen all the complaints about stacked Amazon, eBay and other big branded listings in the serps. It's almost as if the algorithm gives you +5 points, and possibly host crowding benefits, if a stock symbol can be associated to your company.
This is a very, very hostile environment for small businesses in Google. I could spend weeks filling out Google's form explaining why some sites should rank above others. And I will spend an hour or two doing this, but I'm not holding my breath.
I've long believed that the reason why Google posts these feedback forms is to give disgruntled webmasters a chance to vent. After venting, the edge is taken off and some of these webmasters will relax a bit in hopes that Google will actually read what they submitted and act on it. In general, past history has shown me that soliciting feedback from webmasters in this fashion is more of a public relations move for Google than anything else.
Maybe instead of soliciting feedback from "small websites," Google employees should have first taken a good hard look at their search results. They might be amazed at the lack of small websites in many queries. But Google already knows this.
