>I've read here before, don't bump a thread unless you have something meaningful to say.

Where? Your entire argument is useless without this.

>random identity

It's not random... (Look at the source code.)

>the culture of sage

What? There has never been a 'culture' of sage, it just was part of the culture.

>something meaningful

This is relative.

>When people sage they actually don't want people to realize they've posted something?

No, they just sage because it's "polite".

>I can't read the posts.

Use the RSS feeds.

>I have to memorize how many posts there were on that thread to know if any new were added when I last read it

Once again RSS feeds.
