You do realise that this is a million dollars question, right? Which means that it's not so easy to respond. From your list, I would choose communities. But there are already lots of quality ones on the Internet.
If you can create a very unique idea and create an internet buzz, which makes everyone talk about your website, that will draw millions of visitors. It is the idea that will be the deal breaker. SEO only works if you are targeting a specific group of people who are looking for what you offer. Search engine optimization can't replace the traditional idea-based marketing.
