I mean, everything holds on human (in a perfect world) interaction, so your contribution is not for nothing. However I can’t shake of the feeling that trying to be “useful” online is not a good idea.

In general, whatever you posted will most likely be noticed by at least one other person, whose thoughts will be influenced by whatever you posted. So I guess this is already useful in a way? We should continue thinking, otherwise we are just some kind of a biorobot.
