Some people intentionally do this to the comments on their old posts, to avoid having to monitor them for spam and abuse.
I could have sworn I had seen a few articles a couple of years back saying reddit was getting into the embedded comments game like Facebook and Disqus, but I haven't seen them around anywhere.
Maybe I'll play with this during our company hackathon next week.

If it's a new project, I wouldn't worry about the extra click until you start getting some comments (yeah I realize it's a bit circular, but true). My experience is that you will get comments from the aggreggators that the traffic came from, e.g. HN. And maybe Twitter and Facebook.
Most people aren't used to posting comments on websites anymore. But I do get a few comments on Reddit, and it has been worth it.

It's what leads to people getting shadow banned and not understanding why

I ended up using Reddit for blog comments:

Reddit has:
1) a good commenting interface
2) many existing users with accounts
3) a low barrier to a signup for those who don't (you barely even need an e-mail address)
4) an API
The downside right now is that you have to leave the page to comment, but I don't think it's a big deal. It probably lowers engagement a little, but I find that the most commens happen on other aggregators like HN, no matter which service you use for comments.
I also use reddit's RSS feeds, since a few people asked for that.
Reddit has its share of immature users and a culture of snark, but my subreddit has managed to steer clear of that.
