Well, to quote the title of the LatLong blog entry, "I didn't know that was there!" Not sure why they didn't register before. "Landmark Icons" is a good name for them. There was something very enjoyable about just coming across them... almost like playing with a toy train set.
Yes, I see that many icons are linked, but it's surprising how many of the local business icons aren't.
Several businesses and landmarks that I checked have Wikipedia articles. Speech bubbles for these include roughly 60-70 words from the article quoted, much larger than the normal speech bubble. The quotes apparently correspond to the Wikipedia quotes pulled for the Place Pages.
