I am a tad confused about gadgets and widgets. I saw an ad for adsense (a blogger can use this to add ads to their blogs and get money from it and also Zemanthe - which is a gadget that allows you to boost your blogs by enabling you to add pictures, links etc to your blogs. Do I have this information correst? and if so is it wise to use things like Zemanthe? I wouldn't use adsense as i hate ads!!!
