2) What are main tools to recruit Subject Matter Expert (channel to contact, incentives, ....)
Blogs on niche topics take a lot of legwork to grow at the beginning, especially if you don't have an already-existing community as a starting point. Your best bet is to research who blogs on these topics already, and ask them to contribute to your blog. You'll likely want small-to-medium-sized bloggers, not the big shots, because they'll appreciate the opportunity.
By going this route, you'll find people who both 1. know how to write and blog and 2. know the niche inside and out. If you just look for people who know the niche, chances are they won't know how to write blog posts that are interesting to read.
