@Gargron I feel that there is a need for a better means to post comments on web articles. And that too as a post on the person's own account.
As in the past, I think the Mastodon way is to use the reply function for comments on another account.
So when boosting a post, it might be nice to be able to choose whether to pull only the article URL, reply to that post comment, or simply repost (share) them. It would also be interesting to have the ability to list the comments posted to web articles.
