Sure, I appreciate that search engine engineers can't discuss specifics on a public forum, it would be unethical and in some jurisdictions illegal, but unfortunately one-sided conversations rarely get anywhere. Most of us prefer for someone to at least acknowledge a message and failure to provide that simple courtesy can, rightly or wrongly, be perceived as arrogance particularly by people who have families to support and bills to pay but who have just seen their income disappear as a result of actions taken by someone they can't communicate with. However, if anyone from Y is reading this post I have a suggestion to make for what it is worth - for commercial search terms please ignore all blog links and put a substantial penalty on all sites with 'blog' in the URL. I have yet to see a single site that's worth viewing and blogs were never meant to be commercial web sites. This one step would improve the search results considerably. We have to recognise that blogs are a separate entity entirely from traditional websites and so they need to be handled differently.
