I think it is certainly ripe for modern day boys, considering it is vastly unfashionable for girls, so the [name_m]Christopher[/name_m] [name_u]Robin[/name_u] / [name_f]Winnie[/name_f] the Pooh connotation seems to be stronger. I think it is an utterly wonderful name.
I really love this name for a boy. Whenever I hear [name_u]Robin[/name_u] I think of all the obvious [name_m]Robins[/name_m]…[name_u]Robin[/name_u] Hood, Batman and [name_u]Robin[/name_u], [name_m]Christopher[/name_m] [name_u]Robin[/name_u], [name_u]Robin[/name_u] [name_m]Williams[/name_m]. The first [name_u]Robin[/name_u] I met personally, however, was a middle aged woman, and I was actually surprised at her name. I always considered it a boy’s name. [name_u]Robin[/name_u] is a name on our list of possibilities for our baby, if we have a boy. 
[name_m]Both[/name_m] my husband and I love it.
