Yep, spelling and grammer as key, so you're gonna need to work on that. Aside from that, getting traffic to your hub and developing a following are both important and will require a hefty time investment. For traffic, type in a few search terms in Google and then write an article about whatever pops up at the top. Google's already hardwired to do the work for you. As for followers, look up other people's hubs, become their fans, and leave constructive comments about their work. They're liable to do the same to you.
