John Carney — FBNY numbers guy, live blogger extraordinaire — recruited another writer for his fledgling ClusterStock site.

Joe Weisenthal will leave Dealbreaker — Carney's former employer — to join ClusterStock and Silicon Alley Insider. Weisenthal, who's also giving up his full-time gig at PaidContent, will pen the Opening Bell column as well as break, report on and analyze business news.

Carney's note about Weisenthal after the jump.

I'm really excited Joe is joining me at ClusterStock. He's one of the best business and economics commentators around, and he's got a great nose for news. He broke several important stories at PaidContent. I can't wait to really unleash his smarts and talent at ClusterStock. We're already growing our readership tremendously by providing deeper, faster and edgier reporting and analysis of Wall Street than anywhere else on the web. With Joe on board, things are going to get even better.
