I think people just find moderately interesting things online and post them on HN to maybe revitalise them and give them some exposure, or, pessimistically speaking, just in hopes to get some upvotes.

I tend to hope for some discussion about the thing I'm posting that will be like -

1. as an expert on this subject this thing you posted is a waste of time or not for these reasons

2. X is nice but check out Y!

also as a LOCKSS principle I figure if I have a hard time finding it in my bookmarks in the future maybe I can find it in my submissions.
