Here is some basic analysis on WikiLove. The data are from the launch (6/30/11 18:34 UTC) until 7/1/11 22:42 UTC. The analysis includes approximately 248 exchanges (users sending WikiLove to their own pages were excluded). Since this data is very early, it is expected to change as more users use WikiLove.
The following graphs show the wiki-age difference, in months, between senders and recipients of WikiLove. The calculation is based on the registration dates of the senders and recipients. The areas between the red bars indicate exchanges where the sender and recipient are registered within one year of each other.
