One answer, as per my response to that question on my blog, is really because people keep using this concept! Personally, I have no interest in it, it is a fallacy (and I have said that before in a post). It chimes to me of yet another rationalisation to try and extricate from the contradiction which occurs because incorrect presumptions about the very nature of physical existence were made from the start. So, in crude terms, 'let us now separate reality into 'information' and, presumably!, non-information, then the flaw might be overcome and the theory work'. In that sense it is nonsense.
There is a reality. We can only have knowledge of it. If we get that right, then it is the equivalent of reality. Reality does not occur in terms of information, it occurs. Anything that we establish did occur gives us information, obviously. And equally obviously, often what we establish is often the manifestation of something else.
Another answer to your question is I do presume "real things", or validity. It says so in the introduction to my essay. That is, whatever one wants to do with this label, it is presumed that we are concerned with validity and not information which is incorrect, ie does not correspond with reality.
So, if people want to use this term, then the only meaningful definition there can be of it, ie in the context of reality, not some pointless philosophical discussion, is that it is that which is representational of something else (validity is taken as read). It may or may not exist, as such. Light exists, and is an effect in photons based representation of what occurred. A circle may be a valid representation of a reality, but it does not exist. Certain events may be valid and certainly not 'created' by us (as per circle or number)but they do not physically exist as such, but are superficial manifestations of something else, we need to ensure we differentiate that. Or more precisely, discover it as we move forward with knowledge. People can label that information if they want, but it seems to me like a pointless exercise.
