I originally started a website after I lost a digital marketing job, figuring that having a website is a great way to market myself. While job-searching, I realized that I actually hate digital marketing and got into wireless/telecom through a friend. Later I deleted my social media accounts (with the exception of forums/HN) and my website gradually evolved into a personal blog and a replacement for the likes of Facebook, IG, Twitter, etc. I think that sharing things publicly forces me to think through, flush out, and better articulate ideas than I would in on something like Facebook or tweet.

I also use a custom domain for email which still points to my resume (just in case), but I've definitely gotten value from a public facing personal website.
