The concept is like marks on a map. For example: #14 is like several marks on the map (several places found to have breakfast, or something like that).
#15 would be a tack viewed from the top (mark on the map) but it isn't too obvious: doesn't look like a tack. It just looks cool.
Oh ok, that's great idea ! But at first sight I do not find this. The font you use is great, the color too, is any way to modern it ? Like colors more "flashy". I like the idea you use, but not enought explicit for me.
