Thank you, I was about to make the same comment as sqbr but this would help a lot!

Out of curiosity, is it feasible and/or intended at some point to have an indication of what kind of site the link originates from? I know Dreamwidth has implemented userhead graphics for many oft-used sites, e.g. LJ or Tumblr, and I find having that information practical when skimming, but I suppose it would be more time-consuming for the newsletter editors? Also you mentioned upthread maybe wanting to move to Pinboard and that would make this point moot...?
