Many years ago, I made a decision for my website, alvintai.com, to omit the common ‘www’ subdomain when readers visit the site. This is done fairly easily within Wordpress as a simple 301 redirect. You can see this occurring if you curl my site:

When I was first starting my blog, I wondered why anyone would use the ‘www’ subdomain. It seemed like extra characters at a time when everyone was desperate to have shorter URLs, social media handles, usernames, etc. The most obvious reason was because it was simply easier to remember, just in case I ever needed to shout it out to someone who would be quickly out of earshot. Practical, right?
