Blogs
Personally, I don't mind re-directing to a blog if there is no money incentive. That is the spirit of FT. When people use FT to drive traffic to their blog so that they can make an extra buck, it leaves a bad taste in my mouth.
Personally, I need youtube (which I generate zero dollars off of for the very reason I stated above) to post a video; otherwise, I would just stick with FT and flickr for photos.
But when people use FT just to make revenue on their blog site, it is just like the travel agents who use FT to try to make cash by re-directing people to their own travel agency.
