They have hard to find litanies and devotions, laid out in such a pleasing manner. And, if you get called away, beautiful Catholic music reminds you to keep praying! It's so fabulous--I think people could use this in their cars with iPods and iPhones, even Kindle. So, this is one modern thing I adore!
I should mention I believe they were a true harbor for me a few months ago when I began a novena for a special intention. May God bless the webmasters.
