The question "Who is L. A. Balashov?" shows the following curious behavior: Only a few minutes after posting, it became a Google top-hit for the search terms "mathematician balashov":
This makes me curious to ask:
Which MO questions appear on the Google frontpage?
Obviously, this question is ill-posed as you could copy a large-enough fraction of the question and paste it into Google to get back the question as top hit. I am more interested in cases where one searches for some reasonable and small collection of words and gets an MO question that asks a question which is suited to help somebody who searched for these words.
An example of a good answer would be
topology open set
(no quotes), however, the respective MO answer is currently on place three…
An even better example is
resulting in a great MO thread as top hit.
As commented by Tobias Kildetoft, Google personalizes the search. You can omit personal results with this button and you can use the "private browsing" feature to turn off personalization (apart from personalization by country/IP/"whatever Google tracks and is not blocked by private mode").
