[prawn]

Keep in mind that the Dmoz idea was just something I invented on the spot and may or may not be at all useful. An old bookmark I have is this from a few years back:

However, they're hardly niches and would be thoroughly dominated by MFA stuff already with little room to drive in a wedge. You could however pick a few of those, do keyword research on each and then pick a three-word keyphrase from that wider list to think about and focus on? I wouldn't bother going after a single keyword or even two-word phrase as the competition will be too fierce.

Happy to trade emails if you want to bounce any ideas off me. Can't promise anything useful or insightful, but hey, it's free to try! My background is 12+ years web development (backend and frontend) with side projects in forum/community, some passive content sites geared around AdSense plus bigger ideas that I struggle to find time to work on.
