I was curious if there was a way to filter all posts that link to, say, example.com? There are some websites I don't want to see any articles from. If not, I'd like to see such a feature added.
Would it be possible to limit the number of posts that are shown on the home page pointing to a given domain at one time? There have been a few times I've come to Tildes to see what's new and there are 5 or 10 posts that all link to different pages on the same site. I think this would help increase the amount of variety in the stories that are showing and make the site more interesting to users.
