Yes. The "me-too" and "great stuff!" comments I could do without, but a lot of times you get the situation of "I did what you said, and X happened, how do I fix?" and the answer by the owner is just as helpful as the original post.

Or if the post is a few years old but still relevant you can post the tweaks you made in order to get the solution X to work.

So if you're using this as a benchmark of whether or not to have comments, as a reader I'd prefer if you did, even if they're empty 99% of the time.
