I agree with Annette here. A lot don't have much in the way of substance, though they certainly should as blogs allow for more than enough text and copy. I think that so long as blog sites have some personality and those that run blogs individualize them and give them some character, people will come back. Eventually they'll need much more than just free pics to attract and retain folk.
The blogs that do nothing but throw up pics and add nothing of their own to it will fall by the wayside.
