Misspellings yes, but in the instance of Bartelsteain's Blog spellcheck did not pick them up because his mistakes were still words.
Hey meant to say "fly in charter planes" instead of "fly in charter plans", not a huge deal.
He used "There" where it should have been "their" a couple times ("There guards are incredibly quick, there big men are incredibly strong"). Once again spelled correctly although he used the wrong form of the word. Yes that is a pet-peeve of mine, along with to/too/two and you/you're. In the end he's still an undergrad so it's all good.
It's not like he butchered a name...
