You can easily see who responded to you by looking at your comments under your profile.

I can delete my comments... not sure why you wouldn't be able to.

I think HN is about as perfect a site for its purpose as I can think of. It's fast. It's fast on mobile. It's fast. It has really consistently interesting links. It has informed conversations that don't generally deteriorate into childish flamewars. It's hella fast.

You actually can't delete your comments after an hour or so. Try going back through your profile and deleting any old comment.

And i kinda like it for it. Over at Reddit i have seen way too many that pop in, make some kind of comment, and then nuke either the comment or the whole account after a short while.

Likewise, I hate googling for a discussion or review and finding a thread half filled with "This user has deleted their comments with a greasemonkey script..."

Besides, after an hour or so your comment is definitely already in Google and any HN crawlers, and probably on archive.org shortly after that.
