On average there are 111,111 domains registered every day (numbers from Q1 2016).
It is 2017, so if your name .com is still available, go buy it now...you could read the 6 reasons why below, but really, you can come back to this article to confirm the purchase you just made,later.
1. Domains are the real estate of the internet
and space is limited.
2. It is not expensive.
If you haven't bought a domain name from Go Daddy before you can normally purchase your first domain for .99 cents. After that is will cost around $14.99 for annual renewals.
3. If you don't someone else will.
Sure, if your name is unique enough you won't have problems for awhile, but even those names will be bought at some point.
4. Your name is your identity.
Your job title will change, your career path might change, but your name is your brand.
5. Show off your resume or portfolio.
In 2014 I did a Google search of Andrew Berlin, the guy that now owns the South Bend Cubs, and AndrewBerlin.com was at the top of the search. At the time his site was simply his resume. When my name is Googled I want a website I put together to be the first thing people see.
It can be something as simple as your resume.
Graphic designers...you should own your name .com and have an amazing portfolio live. Just get it done.
6. Don't build a website at all.
If you are still thinking..."what would I do with my name .com?", the simple answer is...do nothing with it.
