Apologies if this is off topic, but I've learned to associate a harvard.edu URL in the HN topic with a Philip Greenspun post. I try to avoid his writing, so if other people at Harvard have interesting things to say, I'm not going to find it through Hacker News. The same thing happens with subdomain blogs on github - I can't tell which blog the post is really coming from. The posts are rarely from GitHub, the company. Is the reason the domain is used rather than the entire URL for aesthetic reasons? The short domain looks better. However, I have an internal filter of what I do and don't want to click on and seeing the entire URL helps.
