The feature "Recent activity on the front page" has a subtle bug (or perhaps it is a feature): clicking on the link always takes you to the most recent activity which may not coincide with what's displaying on the front page.
For example,
User A adds an answer. The front page says: "1m UserA"
If during that minute user B added another answer, clicking on the link "User A" will take you to the answer added by the user B
I have a video that may explain this better: Recent activity bug on SO (engine).
edit Oops I cut too much from the start of the video. If you pause it one or two seconds in you can tell the link says: "5m George Stocker" and following the link takes you to Oscar Reyes' answer.
