My main passion is Heavy Metal. As a consumer, I use Twitter to keep up to date with tours, releases, news by following bands and music media. I use it to interact with bands.
I also have a band which has a Twitter account which is used to keep people up to date as mentioned above, and I have a music blog twitter account which I use to review gigs etc...
Partly, but also for communicating. I haven't ever used a feed aggregatior so I'm not sure if there are any other differences...
I also use the trending topics on Twitter to follow the 'real' news. Can you do that in an aggregator, or do you need to have preselected the websites you want to hear from?

I have a pretty good Metal Twitter list here if anyone is interested: https://twitter.com/ColinHugh/lists/metal-news
