This is an uncompelling piece. I believe the core argument is that you should have a personal website a) because the author was unsettled by his own lack of an online presence and b) a side benefit is that he has somewhere to use tech that is interesting to him but not something he can do at work. There's also an offhand comment buried in there about writing practice being good, and an audience making it easier to stick to.

There's not even a real attempt to turn this into a persuasive piece - it's like it started as a post "why I like having a personal website" and then got a new title and intro paragraph. I'd like to see an attempt to explain why the two major points apply to "everyone" - or perhaps the first one wasn't even intended to be an argument, just background?
