B2B Marketing website - up and beyond!?

One of my clients, B2B Marketing, are trying to increase their site traffic by doing SEO and PPC advertising, albeit SEO work has not yet started as I'm doing research based on PPC stats for the last month first.

Basically they want to become a one point source for information and articles about B2B Marketing, also covering jobs within B2B Marketing (eventually), Marketing Events and integreate a B2B Marketing forum called the B2B Hub within their site. They also want to increase subsciption to their offline magazine.

Now, I personally think this site has great potential. The offline B2B Marketing Magazine are doing well, yet the traffic to their site is still relatively low, and the conversions (number of people signing up for subscription is not great). So what I'm asking you guys, what do you think can be done to improve the site? If you look through the homepage, does it grab your interest? Does it seem relevant and insightful? Is it anything that you think is uncessary?

Appreciate any comments, cheers guys!!
