I recently made the decision to put a tiny adsense box in my sidebar. I am currently not working, having been laid off after reporting a work injury (THAT'S a long story), and I'm having trouble finding work that will accommodate my physical limitations. Going on disability is a pretty difficult and lengthy process, but I will be talking to my doctor about its feasibility. I'm also looking into starting a small aquarium maintenance business. I don't need to be wealthy; I just want enough to keep my head above water.
The tiny amount of revenue the ads will generate might help with that. I was going to just have my Etsy store link, but I haven't sold anything out of it yet, so it's not working. I was also pleased with how unobtrusive Google's ads are. I guess they understand that obnoxious, unpleasant ads are repellent to people. I especially hate the "paymybills.com" ads with their horrible graphics and tendency to make my computer vomit!
So, I hope my adsense doesn't offend anyone. I'm very poor right now, and I need all the help I can get.
