The days before ads

I love ads as much as the next person since I do advertising and want to show up when people type in certain terms. However, when doing an article for WRG I had a real problem with ads. Let's say I have an article on convection oven key terms. Well, we're not to link to advertisers since they want informational and definition type links and that's hard to do now without using Wiki (we're not allowed) and a few other competitor sites. Try typing in convection ovens and just see if you can find out what it is instead of where to buy it. If that part was easier I could pop out an article in about 10 minutes but all that searching is taking more than an hour.
