Buy Domains sent it’s January 2013 newsletter, praising the benefits of having a short, three letter domain. BuyDomains recently acquired a large inventory of three letter domains.
Buy Domains says that choosing a domain that states exactly who you are and what you do, is fine as long as it not too long. If a domain is too long then it tends to be less desirable. This is where short, 3 letter domains come in very useful. While a long domain is good to claim your brand and prevent competitors from acquiring that web traffic, you can also consider choosing a three letter domain.
