I think this has already been discussed, but I will give you my point of view..
I like the Buzz.. I like it a lot, and am grateful for the folks that put a lot of time in effort into it. They need to make some money to keep the site up & running. As far as I can tell paying for a banner is the main source of their income.
So, then a company comes along and sees an obvious method of advertising on a site w/o paying for it.. How would you feel if you were the owner of this site, and someone was obviously taken advantage of the spirit of "Recent photo" portion....
I like some of their photos as well, but you cnt tell me their intentions are only to enlighten us with quality shots... My point of view.
I have little opinion of Kayakpro
I have never used them, but it sounds as if you have some experience with them.. I am sure they are good guys etc, I just think they shouldnt take advantage of the buzz..
