That's a good idea, but the create album feature is only available to certain users, this is for a couple of reasons:
1) If everybody could create albums everybody would, and mines could potentially fill up with albums containing only one or two photographs each
2) That would make the site very fragmented, I've already had comments from a few people along the lines of
you haven't got many photos of x y or z when in fact there are dozens, it just turned out they'd only looked in one album.
I know that most would use it sensibly, but by and large the User Album and Archive album should cover most requirements (I hope) but where anybody does want a specific album, e.g. your example of a batch of photographs taken in one calendar period, and if they can't access the create album function then I'm happy to create albums as required.
my orders are to sit here and watch the world go by
