It's true that IE will definitely have problems with the more advanced features. I try to make the site work well for that browser but in the end there's only so much effort I can muster to support IE.
The blogs feature is something that I've wanted to update for a very long time and I keep putting it off for various reasons. I'd like to transition the blog to a simpler format where you enter your entries in a BB code enabled box (like the forums) instead of that big WYSIWYG editor.
