Otherwise it is good.
Did you want a grammar check, or naturalness, or style critique? :)
I'd be inclined to write "go to university", rather than "go to a university", as it is slightly more generic and some like myself went to more than one. NOt incorrect, just a point.
Another factor might be the social network,
"the" seems a little funny here, though not incorrect. Seem as if you are saying, ... the social network of that person. ("the" ==> definite)
Another factor might be social networks, ?
.. by which people can draw .. also ok, but could be neater as
.. might be social networks, which allow people to draw ...
Not wrong, just a different approach.
