I would say yes, keep posting, because even the practice of posting will get make you better and better at writing interesting content. Also, keep using sites like reddit, stumbleupon, digg, even mixx if you can stomach it. Use all the news sites etc and get an idea of what people like to read, and if there are interesting news stories.
Also look ahead in calendars to when there are up coming events, and write about them. Write about what is going to happen, not what people already know about, and then you will be writing about “news” not “olds”
I think you need to consider your target audience before writing. Who are you trying to reach? If you want to build a following of contemporary rockers, then Dream Theater sounds like it would get some bites. There is a multitude of web sites and news stories on the internet. Make your stories stand out from the rest. Read competitors such as reddit.com and see what you can do differently- better. Then build your following.
