Logical Media is an affiliate marketing company. Through them, I can run small ads on blogs, twitter, facebook, email, etc and get paid. It doesn't pay a ton, but ads aren't my main focus.
When I choose ads, I make sure to choose things that I already use or would willingly use. There are some ad campaigns that I just will never run because they go against my beliefs. With Logical Media, I can choose what ads I run, when I run them, and by what media outlet.
For example, any time I list coupons that I am printing, I use a link from logical media. I get paid $.40 for each print session that happens after someone clicks through my link.
