The idea sounds good, I think that some more sites like this are indeed needed.
I don't like the domain name, imho sounds newbish. Even Coin5n or similar would be better. But this is me.
The news area was attempted here and there, but either abandoned, either not enough relevant news where I've checked. Something that I'd like to see would be RSS feed with the news. That would be something I'd surely use, but I don't know what would be your site's benefit. Maybe adding the tickers too to the RSS feed too?
However, it looks like a good project. Keep it up, good luck!
