Adam - congrats on the funding and getting out of the Beta stage. Awesome product, but since you asked for features, how about adding some more 3rd party integration options? You already do Hoovers for company information, but it could be applied more generically to other types of news. i.e. breaking news about topics/keywords in my e-mail.

If you make it optional, it won't be annoying. But I can see it add value because I sure as hell want to know if there's any news about subject X if I'm about to send an e-mail about X to someone.

BTW, I wanted to drop you an e-mail about this, but couldn't find your contact details in your profile or on Xobni or on your blog!
