Your thesis is that you have control and ownership of your content; misspellings tend to make it look like you don't take your own advice to heart. I'll grant that it would be unfair to evaluate everything under a microscope, but there are pretty obvious mistakes that a pass-through should have caught. On your "about" page in particular there's a handful of mistakes that you should have caught.

It's really mean-spirited to cherry pick embarrassing examples, so I'll email those to you privately and publicly suggest (to everyone with a site) a quick pass through of the static content (don't bother revising all the blog posts unless you have plenty of time; just be more careful with your writing in the future and do several pass-throughs).

The value in a personal website is that the content of the first search result is all yours (as in, rather than letting Facebook be the first result with all the embarrassing stuff your friends might tag you in, the first result will be entirely self-sourced). Arguably, that puts even more onus on you to be absolutely confident in the quality of that result, because people are expecting this to be your best foot forward.
