Grammar Nazi

Last night I was reading through the "literature," getting ready to register for the BreakForth conference. I've gone for a few years now, and it's always an experience - usually a good one! There's classes in songwriting, leadership, vocal technique as well as all the ones I don't take, like men's ministry, children's, drama, and a bunch of other things that are currently slipping my mind, because they don't really interest me (shh, don't tell.)
What I noticed, though, was the ridiculous number of grammar, spelling and punctuation errors within the flyer. It's a huge conference - nearly 7000 attendees last year. I wonder, with that many people, and that much money flowing through (though I know it's not as expensive as it could be,) how they managed not to hire a competent editor. There's really no excuse for using an apostrophe to express plurality!
Now, I know that I've made errors in my writing, and of course on my blog. But since I'm blogging for fun, and since I don't have thousands of people reading, I don't feel it's as important. Of course, I'd never purposely be lazy with my grammar, but when you're blogging at 2am, sometimes the little things slip. But trust me - I still know the difference between their, there and they're. Because, really, bad grammar makes me [sic].
