No, I’ve explained this in the post. they’re to be flagged and hidden once someone updates them, and harder to answer ones are to be upvoted to be kept on top of the thread. This is to keep things organized and clean, and draw new eyes to each individual post. It’s easier to maintain than having to constantly edit posts.
If I had an answer with 100+ links, it’s harder on the eyes. It’ll discourage people from wanting to read it. Imagine a new user doing this with really poor formatting; it’ll be just awful. And then, someone will have to hide every single comment saying “I answered this”, and edit the post. The person stating they commented it would have to be more specific about which post. The amount of edits will clog the activity feed, and the excessive comments will slow down the site. If they’re individual answers, PM can eventually delete the old hidden ones (alongside the comments) to keep things functional. Having them be hidden prevents flood in activity stream. And the organization of it will encourage people to look and answer.
