I have a blog that focuses mostly on recipes but not all my posts are recipes. Schema creator gave me the perfect flexibility to add schema to my recipes and leave it out when I want without changing the format, look, or feel of my blog.
There were a few bugs in the plugin that I let the creator know about right away on GitHub and he fixed them and rolled out a new version of the plugin by the very next business day, sometimes sooner!
Since the CSS can be customized I had my web gal match the CSS to my blog's theme and it looks seamless.
So far I have only entered one recipe with the schema creator and guess what? A rich snippet already shows up on the first page (#6) in google for my recipe name keyword search.
I have not tried the other schemas available such as reviews, business . . .(etc.) but I have never seen a plugin so well supported (on GitHub) that I am sure that with a little patience and communication with the creator you can get what you are wanting.
I can't imagine an easier way to add schema to my blog and I know that schema creator by Raven is going to help me to compete in the search engines without having an entire staff devoted to SEO.
Thank you again Norcross!
P.S. Here is an example of a post that I made with the recipe Schema Creator by Raven, I thought it might help people to see a screen shot. I did not use the default CSS but instead had it modified to match my existing blog's style: http://rawglow.com/blog/2012/12/26/moroccan-raw-carrot-salad-sweet-crunchy-spicy-yum/
