I've got the results of a test run of search results I did in October 2000 sitting on my computer. The Google search results from today are much better than from October 2000. I do think it's fair to make the point that overall Google is much better--and overall spam is much lower than 5 or 10 years ago--before we drilled down into responding to the blog posts from the last couple months.
I'm sure that Google does better than it did in October 2000. They'd be something horribly wrong if that wasn't the case. That's not relevant to the specific concerns people have about what's happening here and now.
Sorry, I was responding to the "They'd be a lot more credible without the corpo-speak junk in the first paragraph." by trying to defend that the statements in the first paragraph were true.
Regarding the specific concerns that people have been raising in the last couple months, I think the blog post tried to acknowledge a recent uptick in spam and then describe some ways we plan to tackle the issue.
