Isn't there a risk to get your blog blocked in corporate environment though? If it's a technical blog that would be unfortunate.

That depends on how terrible the middleboxes those corporate environments use are. If they only block actual malicious pages, it shouldn't be a problem unless the user un-hides the links and clicks on them.

There's a good chance corporate firewalls will end up blocking your domain if you do this but that sounds like a problem for the customers of those corporate firewalls to me.
