I'm working on so that the database is collected separately from blogs to text file for your program (I use this additional program for the collection of links).
To search in Google, I use the following query:
intext:?powered by wordpress? +intext:?Post a Comment? -?logged in to post a comment?
Your program works with certain kinds of blogs.
Prompt which option to add a request to immediately find only those types of blogs that supports your program?
