The forum is very productive at generating relevant content and creating pages that rank highly for specific or targeted search terms. Within a website that is very general (internet business, web marketing, make money online) and in a highly competitive industry - you reach the niches with individual categories and pages.
On the other hand - and what I believe you were referring to - you can create smaller highly-focused sites on specific niche markets. I can see this being a profitable model also, and have heard a lot of enthusiastic talk about this lately. I look forward to hearing what others have read, or tried, or just thoughts on the topic in general.
