For me, personally, this is not absolutely necessary, only for view cards. For every other cards I prefer organizing by subject.
But IF a user has different albums it’s really helpful if these albums are in alphabetical order.
Once I stumpled into a Flickr profile with around 300 albums (each with around 200+ pictures). Postcards and fotography. In order of creation date. This would drive me really crazy and in case I’ll ever get this user on official site it will be the 1st time for me refusing looking through all the albums.
I have my albums organized (still not complete, I always try to improve it) but this is also for me really helpful not only for those who draw my address.
