Well, typing and deleting lets me think thoroughly about where I stand in matters and what arguments I use. So in a way, it sometimes makes a difference for myself even if not posted.

fwiw i like reading long ass comments. usually there is something useful or insightful in there.

way more than i like reading 'ok boomer' comments.

but totally get that it doesn't make a difference and the vast majority of the replies will be of the 'ok boomer' or 'u suck' variety.

Your comments look good. I think you should do more.

Hardly any comments here are important, but getting the conversation going, and then continuing requires the contributions of as many of us as possible.

I mainly post photos, and I love when someone even takes the time to say wow this was really cool or this pic made my day a little better.

Everything you do here feeds the process of making this a better and more active place.

Same, but because I'll make someone mad by posting.
