Moderators of HN: please stop changing post titles
I would prefer that the alternative of posting either a link or explanatory text be changed to allow both.Often a title, original or otherwise, simply doesn't provide sufficient context to clearly explain a link.  A few well-chosen words of prose could help here (more so if the text could be editied / modified while the post was sitting in queue).  Gameable?  Perhaps, but we can vote down / flag in that instance."Heat & Thunder" was pretty non-obvious to me, and until I read the comment here about the data visualization, struck me as particularly non-interesting.
