I did that when I was younger and internet forums we're still a thing. The difference is that I had to do actual research, which often took me half an hour or more, to solve the problem for the asker. I got knowledge and "the feeling of being a notable figure" as you have said. The other side for the answer. I believe my answers were good.
The difference is that nowadays people can just skip the research part and copy-paste Llama. No value added.
