Unfortunately I have to agree. It is becoming increasingly common to see that

1. few comments are written and
2. comments are not replied that often.

Replying to posts and comments takes time. Many people invest their time in another post rather than actually communicating with other users.
Unfortunately, this is often supported by the fact that posts are rewarded better on average than comments.
The other side of the coin is that many are surprised that they are not noticed. They don't realise that the only way to get noticed on a platform like this is by interacting with other users.
So they wait for a vote from the community curators or the SC and complain here too when this doesn't come in sufficient numbers.

So my tip (and wish):
Commenting gets you more attention in the long term. The more interested people know you on the platform, the more people read the posts and the more votes you get. I think a post only becomes valuable through good comments.
And: answer and vote for meaningful comments that you have received. Imagine you speak to someone on the street and get no reply...
