I don't know what brought this question into my head but it's something I'm genuinely curious about now. How often do you preview your text before posting it? I've gotten into the habit of previewing the majority of my posts, largely because I spend a lot of my time here via mobile browser, and autocorrect can be a cruel mistress. I really can't stand typos in my posts, being a stickler for good grammar, so it's just something that's become a habit more or less every time I post now. There are some cases where I don't, but that's usually for very short posts that don't really need any proof-reading. Sure, the edit button exists for a reason, but I like to avoid it whenever possible.
