Wikipedia entry on information: "At its most fundamental, information is any propagation of cause and effect within a system."
I'm fine with not referring to information as non-physical and/or immaterial. The point I don't want to lose though, is that information is different from, say, the tree in my neighbor's yard.
As Deutsch said, information, while physical, is substrate independent. Information is like a wave propagating through various mediums.
The wikipedia entry also had this to say about data and knowledge as they relate to information: "
Information (shortened as
info or
info.) is that which informs, i.e. an answer to a question, as well as that from which
knowledge and
data can be derived (as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts). As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an
event horizon, for example), while in the case of knowledge, information requires a cognitive observer."

I know that conceptually, it's hard to imagine what it's like to be information. However, I think consciousness as information is a viable potential solution to the Hard Problem.
Why can’t the world’s greatest minds solve the mystery of consciousness? | Oliver Burkeman | Science | The Guardian
One spring morning in Tucson, Arizona, in 1994, an unknown philosopher named
David Chalmers got up to give a talk on
consciousness, by which he meant the feeling of being inside your head, looking out – or, to use the kind of language that might give a neuroscientist an aneurysm, of having a soul. Though he didn’t realise it at the time, the young Australian academic was about to ignite a war between philosophers and scientists, by drawing attention to a central mystery of human life – perhaps
the central mystery of human life – and revealing how embarrassingly far they were from solving it.
The scholars gathered at the University of Arizona – for what would later go down as a landmark conference on the subject – knew they were doing something edgy: in many quarters, consciousness was still taboo, too weird and new agey to take seriously, and some of the scientists in the audience were risking their reputations by attending. Yet the first two talks that day, before Chalmers’s, hadn’t proved thrilling. “Quite honestly, they were totally unintelligible and boring – I had no idea what anyone was talking about,” recalled Stuart Hameroff, the Arizona professor responsible for the event. “As the organiser, I’m looking around, and people are falling asleep, or getting restless.” He grew worried. “But then the third talk, right before the coffee break – that was Dave.” With his long, straggly hair and fondness for all-body denim, the 27-year-old Chalmers looked like he’d got lost en route to a Metallica concert. “He comes on stage, hair down to his butt, he’s prancing around like Mick Jagger,” Hameroff said. “But then he speaks. And that’s when everyone wakes up.” ...
