How do you feel about link-only posts in IH?

Personally, I think if you have time to copy and paste a link here, you should also have the time to comment on why it's useful, or how it applies to anything IH-related. The vast majority of links people post don't seem applicable to this community, or just self-serving, but perhaps that's just my own perception. I'd rather see a minimum post length myself, but that's just me. How do you feel about it?
