How to get the list of the top facebook pages?

I'm curious if there's anyway to get a list of all Facebook pages with their associated likes/followers count? I've noticed that there are sites that provide this data (e.g. Top 100 Facebook pages) but I'd like a more comprehensive list.

Social meta tags when several articles on same page

This is my first attempt with social share buttons on a classic HTML website (not a CMS).
I understand that social meta tags are now the way to go as you have more control on what you are sharing (you can have more control on the title, the picture, the description, the content type etc..).
What I don't get is how to share a specific article only when you have ten articles displayed on the same page.
All the tutorials I read about sharing buttons are dedicated to a whole web page but I would like to share a specific section of the page per button, not the whole page (one page = 10 articles = 10 share buttons).
How would I achieve that?
Thank you.
(Bonus question: are social meta tags shared by FB, twitter and linkedin or are they only dedicated to FB?)
I don't know if you are still struggling with this, but I've just been thinking about a similar-but-different problem, with a one-page site where the content is swapped out dynamically so that it is not possible to change the og: tags in the header.
The solution requires generating individual pages for each specific article that have their own with dedicated og: tags. Then in your page which lists 10 articles, each one has a share button where the link points to the specific article page, e.g. <a href="https://www.facebook.com/sharer/sharer.php?u=http://yoursite.com/article1.html">.
When some clicks the share button, facebook will crawl the target url for og: tags, not the page you are currently on.
In your case the solution is pretty straightforward, as you presumably have individual pages for the articles already. Mine is slightly trickier because I have to generate extra pages which won't be navigated to from my site but exist for facebook to crawl (and to display the right content when people arrive via the social shares).

Comments not crawlable by search engines?

I was wondering if Search Engine spiders can see the comments, when I open the source of the page the comments are not showing up (same as with disqus), so I'm assuming when the search engines crawl the page they won't see the comments either? Is this assumption correct? If so, is there a way to change this?
Found the solution:

How can I get an SEO boost from the comments left on my site?
The Facebook comments box is rendered in an iframe on your page, and
most search engines will not crawl content within an iframe. However,
you can access all the comments left on your site via the graph API as
described above. Simply grab the comments from the API and render them
in the body of your page behind the comments box. We recommend you
cache the results, as pulling the comments from the graph API on each
page load could slow down the rendering time of the page.
Only what get thrown to a crawl engine the crawl engine can see, hence these comments should be outputted in able to get crawled and saved into the SE database or whatever it uses to collect data about websites, you might check the headers the connection request came from, if it belongs to a crawl engine and that's called a user agent in our case humans (browsers), here you can find a way to detect crawlers using PHP, after detecting it you force the comments to be shown in order to get crawled, here also a good resource on how to deal with crawlers from Google itself.
Now if you're talking about Facebook comments, it's impossible to let them indexed by the crawler or SE, when a crawler attempt to visit one of the Facebook pages it won't be able to see users' data because of the login page, and if you are talking about Facebook plugins you may do what what I suggested above, article talking about Facebook comments crawling.

How to get users who liked my website pages?

I am generating Like buttons for each of all my pages, objects or something that can be liked. After that I want to display on a page called "User statistics" all users who liked pages.
Searched web - nothing interesting.
Need a server side solution, no JS.
No. There's isn't a summary page.
But you can see number of shares/likes by using Graph API, for example
http://graph.facebook.com/?id=http://stackoverflow.com

changing site.master page dynamically based on url

I have a website say http://www.xyz.com.
Now I also want to have this same website as an app in facebook say http://apps.facebook.com/xyz.
The only difference will be that in my site I want to have my links on the right side of page vertically but in my facebook page I want to to have the links in a horizontal bar.
As the website is the same it would be best if I could have two master pages and call them based on the url.
Any idea if this is possible.
Thanks
