Tag Match Ratios
You should change / add the way you display tags numbers in the main person screen. So rather that it just being the number of similarities, it’s a ratio between similarities and the total number of tags the other person has.
Right now if I see a large number I immediately ask if the person has a billion tags and they usually do, but if they had a smaller number of total tags and a larger portion of those tags matched that would be something I’d be interested in knowing right off the bat.
