Thanks for your New Year's wishes Breadcrumbs - Happy New Year to you too.
We have approached many bloggers offering them the chance to index their own blogs if we are not likely to get to their blog ourselves soon. Some (just a few) have expressed interest in doing so and of those only two have completed it. Some have given up and some are persevering (very slowly). We would love for more bloggers to do so - as you say, it introduces their blog to a whole new audience and drives traffic back to their blog.
Even more inexplicable than bloggers not wanting to index their own blog are that two blogs so far have said they don't want their blog indexed by EYB, even though we were doing all the work (at great expense!). Now that really is strange - someone offers to create an index of the recipes on your blog and drives traffic to you and you don't have to do a thing or pay a cent but you say no? Weird!
Our primary focus is still very much cookbooks and many new books are being indexed every week. We are also indexing 28 different magazines every month (as well as working our way through the archive for some of them). If you check the Library books tab you will see new books are added every day.
