Right now this thread is new, only just getting started, but it has the potential to become another very popular, years-long kind of thread similar to the Photo of the Day thread, for example. Right now, sure, it doesn't look as though it would matter whether or not it is pinned/made a sticky but further on down the road as additional threads are added to that first page in the Digital Photography subforum and things shift to the second page, it would be a good idea to revisit this request/suggestion. (Just speaking from my own experience on another forum, where we've got a long-running thread similar to this one here.)
