OP probably misspelled twitter.com and directigveaway.com bought the misspelled domain. Pretty common tactic.
Twitter is only a waste of time if you don't like having direct access to professionals in your field or feedback from clients, don't care about making sure your marketing is targeting zeitgeist effectively, don't understand how to leverage search/hashtags, don't understand traffic funnels. Looking at it like a "social network" in the vein of Facebook is missing the point entirely. End derail.
