Of course you do. The sad fact is that some drummers and companies are more active with their fans and consumers on Twitter than other forms of social media. In order to interact with them I will need a Twitter of my own and eventually I'll have to keep it updated regularly as well.
But as a concept it's stupid because everything it does can be done better on Facebook. It just got popularised because vacuous celebrities don't need more than 140 characters to express what's going on in their heads.
