一个 Discourse 实例，两个博客？

It is feasible to use a single Discourse instance to host the comments for both A and B? I might, for example, just give each blog its own default Discourse category in order to keep them separate. I certainly don’t mind having commenters from both blogs in the same Discourse site.

That should work just fine! If you are adding comments using Embedding Discourse Comments via Javascript, you can set each blog category on /admin/customize/embedding
