Sure, I can explain you why I did that - The reason I did that is because:
I want topics to be displayed in full page.
Example:
If I keep the /{PageName} in url,
You can see the discussion board page looks like this:
HERE
And, when you go inside the board, the topic page look like this:
HERE
(You can see the the topics are being displayed in the left column and then when you click it, it still display the posts in left column which is small area for posts that I get as everything gets condensed)
My requirement:
I do want my discussion board page look like this:
HERE
The only difference I want is that when anyone click on topics, the topics should be displayed like this in full width:
HERE
This is why I changed the url because I want monox/pages/socialNetworking page to be used instead of same page where topic is clicked as {PageName} keeps the user in same page structure and only change the content.
