I am aware that discourse allows deleting ones post – I used it myself once to remove a duplicate reply.
However, what has happen a few times now is that someone started a topic, got one or more replies and then deleted the thread. I do not think that is useful.
Example 1: “Qubes review from qubes user + suggestions” 12/8/20
The OP had reached some incorrect conclusions and I started to point that out to him. All in all nothing embarrassing and – this is my main point: potentially useful to educate others and find ways to improve documentation.
Example 2: “Split-GPG setup failing; Qubes_GPG_DOMAIN not setting”
The OP referenced the documentation, unman asked a question and the OP responded that he’d already checked the policy file, while pointing out that according to the documentation it should just work. I checked the default policy and which is “ask” and the documentation and on the surface it seemed the OP had a point.
Then I wanted to follow the link in the original message to see the screenshot on the forum … at which point it turns out the entire thread is gone!
I suppose the OP figured it out and deleted his post. I do not think that is useful at all.
We all learn through mistakes. Or own and those of others. This is what makes mailing lists / forums of this kind such a useful place. It is an environment for growth. You spend time looking at questions and problems of others, try to figure out how to help them and learn in the process.
While I see the convenience in being able to edit or delete ones post (typos, clarifications, double posts), I think overall it harms.
What do you think?
