I created a small one-off blog a while ago for a single hiking trip I made, and as you might imagine, I link to several product sites for the equipment I use - plain ol' links, not affiliated or anything.

I did so, but I never really understood why a company would reduce business opportunity (however minute) by asking me to do this.
