I think we can make the distinction between complaining and venting at that point, and the second one would at least serve the purpose of putting your mind at ease for some time. And to be fair I don't think your example is particularly well suited here, because changing the patent system would most likely need more support than just your own actions, which can be gathered via HN. It can also lead other people to reflect on the issue and take actions themselves. I would still classify that as complaining. If I had to choose an example of venting, I'd say that I could go on HN to complain about the neighbor's dog that barks all day long. Nothing would come out of that, and I don't need anyone supporting any action on this problem, so it'd be venting.
