I am usually pretty reticent to put my email address on the web, as spam bots can easily pick up my digets and start sending my all kinds of junk. But this helpful little tool, TxtNinja, can embed your email address, phone number, or whatever you want to keep from the bots, into a picture.  You can then post that picture on the intertubes, without (much) fear of becoming the latest cash cow of the spam industry.
