As I wrote, I'm looking for some suggestions about how to do the next thing:
This is the scenario: I set a Site Collection up with several blogs as subsites. What I want to do is to show on the main page of the site collection some entries from these subsites.
To do this, I created a Content Type with some Columns as "IsVisible on home" for the blog's entries. I also use to show the information a "Content Query Web Part" where I set the condition to be showed on the home page. This WebPart also allows me to configure css styles, setting the ItemStyle.XSL file. But the point is that I don't really know how to show the number of comment for every blog entry. Can someone give me a clue?
PD. I'm using Sharepoint 2013.
