LWGLIN's Journal: PDF to become an open, ISO standard

This is great news: "Adobe Systems Inc. on Jan. 29 announced that it has released the full PDF (Portable Document Format) 1.7 specification to AIIM, the Association for Information and Image Management. AIIM, in turn, will start working on making PDF an ISO standard."
Now I won't have to start endless discussions with people not liking PDF because it is 'proprietary', an argument that IMHO made no sense because Adobe has always allowed developers to use the PDF Reference as described in section 1.4 of the PDF Reference.
But what do Slashdot readers think about this evolution?
