differences between pages an blogs link creation

Hello

i do not understand the following, why are the links generated if i write a blog post formated like:

http://meet.divexit.de/pg/blog/admin/read/144/fallschirm-packanleitung-propack

and pages like:

http://meet.divexit.de/pg/pages/view/92/

 

i like the blog way much more.

 

offtopic:

why do i get redirected to the index/dashboard if i klick the blog link title?

for example: http://meet.divexit.de/?offset=10
