I have discussed this before; how difficult it can be for a band to manage their online presence and how difficult it can be for a fan to find music and bands online. Always, always have your own official website before you begin to tackle all these other sites.
Speaking from personal experience; as a very active music fan I look for a artist website first, then I do a Google search and look on Facebook and MySpace. Do I take the time to start looking on all these other sites, nope. If you have no official site your chances of being found go down dramatically.
Watch this video, how many of these sites have you heard of?
