Sorry, I can't answer your question. The difference is indeed puzzling, with so similar questions treated so differently only a week apart.
I will however state my stance on these questions. They both provide useful information to a traveler who is going to drive to some place and will need to park his car. The question is even directly related to the means of travel. So I don't see how they can be considered off-topic. In such non-obvious cases, when voting to close, you should really leave a comment explaining why you're voting to close.
A very simple web search directly led me to http://sjdowntownparking.com/parking-map, which has all the details about where to park in San Jose. This site is linked from the San Jose municipality website, too. But what both these sites lack is a good overview — how hard is it to find free parking? Does it matter how long you stay? Does it depend on the time of the day? So I can't see a reason to downvote for lack of research, either.
