There's several reasons it could happen, many of which that aren't negative. As a couple examples...
Someone reading the thread may think they have nothing to add, so rather than a "i've got nothing" or "Sorry, not my thing," they just don't post.
It could also be that they feel like they don't have the slightest idea what to say, or how to help, and rather than flailing at it they just don't post.
They could be thinking about responding negatively, but rather than that they just don't post.
Paranoia. Can't really go into that.
I'm sure there's more, those are just a few reasons I've had when I've refrained from replying in the past.
If anything, just knowing that someone has read what I've written has been helpful for me at times. Sure, they may not care, but someone's aware of it if nothing else.
