I love math, but can't say I ever learned to love LaTeX. I understand how it was useful back when my main editor was vi, but these days with editors like Word that just let you see what you're doing, I don't really get the point. That said, when I do have to work on a TeX document (because of whom I'm working with or conference format or whatever), I've found LyX to be a good WYSIWYG editor. There's definitely a learning curve, but the documentation is good, it's free, and I've always managed to get the formatting I want eventually. Good luck with the blog and I hope you learn to enjoy the math. Once you know the math enough to trust it, it's a great comfort to be able to tell yourself "mathematically this is right, so there must just be a mistake in the code."
