I think a better solution is to buy a short and easy to remember domain name and link all your official identities from there. This also gives you better control in how your name appear in search engine results. But make sure you include your full name on your home page and in your linked social pages. It might also help if your social pages links back to your homepage.
Having your own page is also useful for tracking visitors with Google Analytics or similar. You might think it is not necessary for a small homepage with low traffic. But it's interesting to watch new data coming in after handing in a resume. Some employers will access your address directly, other will find you trough search engines. If there are no visitors, you know the employer hasn't bothered investigating your online references. How that is interpreted is up to you. In my experience, employers rarely care to dive very deep into the links you provide them. If they do dive deep, perhaps they call your references next.
I believe what employers care about is first impression. A good looking domain name is better than shortened URL to a free social site.
