I've contacted them for more details and will report back when they respond. The site says:
Geneally.com is the world's first dedicated genealogy and family search engine, built from the ground up to create a useful resource for anyone researching their ancestry.In November 2008, Geneally acquired the former genealogy news site www.rssgenealogy.com.
Hundreds of new links are added each day. If you run a genealogy-related website, do contact us and we'll do our best to add the details of your site to our database.
There are numerous links up now - Tracing the Tribe is included - and more are being added.
I've just emailed them about adding the International Jewish Graveyard Rabbit and the general topic MyHeritage Genealogy Blog.
