Probably around 99% parseable. I run every post through jboski/jbofi'e before publishing. But sometimes I return to a post to make small changes as my Lojban improves & don't re-check it. As for correct -- as in expressing what I meant to express -- well, I'm still a beginner. If there's a sentence you can't figure out, skip it & keep going; maybe the context will make it clearer. You can always send me a note or comment with questions. I'd like the text to be as correct as possible so that when people do usage searches & it comes up, they can rely on its quality.
