Yes, content is still king! I attended many sessions on Search Engine Optimization, Paid Search, Microsite development, even Social Media sessions, and one theme rang through-out the entire set of sessions:
It's all about relevancy! If you write targeted, relevant content -- that hits your audience on the mark, then search engine optimization, driving conversions, etc., will be much more effective.
So, it's all still about the content. But it isn't about you, your organizations, or your products. It's about your customer -- whatever you write, it MUST be relevant to your audience. It must be understandable and valuable to THEM. That should be your measure.
I met a cool guy at the Summit, Joe Pulizzi - who runs Junta42 - which is all about Content Marketing. His site also has a list of the top content blogs, where you can find out the latest on putting together relevent content that works. Joe also has his own blog -- and a good post announcing Junta42Match, which might be perfect for helping you with writing content for your targeted segments (see my previous post here)!
