I get that the concept of Tomahawklet, while simple, can be confusing to some for the sole reason that people just aren’t used to things “just working” like that. See what a decade of using media players that weren’t designed to operate in a web world will do to you? So, for our first “tip & trick” I’ve made a quick screencast to demonstrate just how Tomahawklet works in conjunction with Tomahawk. (Disclaimer: the audio is not very good on this screencast. I promise to make them better in the future.)
Check out the list of currently supported sites. Have ideas for others, let us know over in the forums, or better yet check out the project on Github and write your own custom Tomahawklet scrapers!
